Rohan arrives 1 second too late, and waits 299 seconds.
Rohan arrives 2 seconds too late, and waits 298 seconds.
...
Rohan arrives 298 seconds too late, and waits 2 seconds.
Rohan arrives 299 seconds too late, and waits 1 second.
Rohan arrives 300 seconds too late, and waits 0 seconds.

Rohan arrives 301 seconds too late, and waits 0 seconds.
Rohan arrives 302 seconds too late, and waits 0 seconds.
...
Rohan arrives 539 seconds too late, and waits 0 seconds.
Rohan arrives 540 seconds too late, and waits 0 seconds.

So, add the 299 different delays (299, 298, ... , 1)
to the 241 non-delays, and divide by 540 seconds,
to compute an "average" wait-time.

The red lights came on as I approached railway crossing,it was too late to brake,will I be fined

If the train didn't hit you, you and the engineer are about the only ones who will know, unless a cop saw you, in which case you would already have the ticket.
As of yet I haven't seen any traffic cameras that auto-mail you the fine for railway crossing infractions.

4 men approach a rickety bridge at night. They are of varying ages, and as such take different amounts of time to cross the bridge. Since they just have 1 lantern, and only two men can cross at one time...

perhaps the man that can cross longer minute is old.. so u have to carry that person.. so then cross by two's each one of them carry a person that walk slow..and you cant leave one or two behind co'z there's only one lantern

You will have to login to the Safe mode option and run a spyware scan.

Kindly download and install Malware Bytes application which is a freeware and easily available in web. Once installed follow the steps below

Step 1: Shut down your PC completely.
Step 2: Turn on the Power button.
Step 3: As soon as you turn it on start hitting the F8 key on your keyboard until you get to a black screen called "Windows Advanced option". (If you don't get to that that screen but you end up reaching the blue screen than that means you have delayed in hitting the F8 key. start again from step 1.)
Step 4: As soon as you reach "Windows Advanced option" use your down arrow keys to choose an option called "Safe Mode".
Step 5: Select that and HIT ENTER.


One you are in the Safe Mode Run the Malware bytes scan (Quick Scan)

2007 Hyundai Santa Fe Limited

Hey all,
I was able to get installation instructions for the cross bars from http://www.capitolhyundai.com and from http://dealerfit.com.  Thanks much to these folks for providing a pdf of these instructions free of charge!
Below is the text from the instruction set that worked best for me.  The other instruction set was nearly identical but it had an alternate Step 2 which involved using a small plastic pry bar.  I added that alternate Step below in the instruction step.  Hopefully I'm able to insert the image of each instruction set so that the Figures are visible.  Its actually not that easy getting the rear rail covers off and its pretty easy to crack them.  I'd recommend gently rocking the covers for a couple minutes in order to loosen them up.  Once you get the covers off, the rest of the install is a breeze and can be done in 2 minutes.  If you have questions, go ahead and contact me.  I also took several photos of my install and that might be helpul.  Cheers!

SANTA FE 2008 PIN U8210-28000 Cross Bar Assembly Installation Procedures
Kit Contents: • (2) Cross Bar Assemblies Required Tools: • Flat Head Screwdriver
INSTALLATION INSTRUCTIONS
1. Carefully unscrew and remove radio antenna. 2. Grasp the rear rail covers with both hands. Squeeze and pull up & inwards (toward the center of the vehicle) to remove covers. Take care not to break off the tabs by lifting the rear section of the cover first (Figure 1). Be careful not to scratch, damage or dent any painted surfaces. DO NOT PRY AGAINST THE VEHICLE BODY, THIS CAN CAUSE DAMAGE TO THE VEHICLE. 2. - Alternate Method - Locate notch in rear of each cover to insert plastic pry bar.  Remove cover by prying up (with tool) and lifting rear at 45 degree angle (Fig 1). Be careful not to scratch, damage or dent any painted surfaces. DO NOT PRY AGAINST THE VEHICLE BODY, THIS CAN CAUSE DAMAGE TO THE VEHICLE. 3. Check assembly clips for damage and dislocation. Replace if necessary. 4. Open the lever on one side of front/rear cross bar. Gently set the cross bar, with the arrows facing forward, into the channel of the side rails (Figure 2). Guide both sides into the track. 5. To adjust cross bars, open lever and place cross bars in desired location. Close lever (Figure 3). Try to move bars forward/back until they lock into place. 6. Reinstall rear covers by holding cover at a 45 degree angle and inserting the front tab into the rear of the roof rack. After aligning, snap cover in place (Figure 4). Be sure that the rubber lip does not interfere with the covers, and that the covers are fully seated. 7. Reinstall the radio antenna. Note: To remove the cross bars, remove the antenna, remove the covers, open lever of cross bar and slide to end of rail. Hold down locking fingers (on both RH/LH rear rail supports) with a flat head screwdriver (Figure 5). This will allow removal of cross bars from the rails.
