[edit] Hints

Hint One
    You're probably thinking that this is a really bothersome calculation problem.

    Actually, there's a really easy way to work it out. Just make sure you get all the numbers right before you start.

Hint Two
    A 100m train travelling over a 400m bridge in 30 seconds. So you have to divide 400 by 30, right?

    Well, the train starts travelling over the bridge the moment the front of the train is on the bridge, and it finishes once the end of the train has moved off the bridge.

    How far has the train travelled in this time?

Hint Three
    Can you see that the train must travel 500m in order to travel completely over the bridge?

    If so, the rest is easy. 500m is 0.5km. 30 seconds is 0.5 minutes.

[edit] When Failed

Too bad!

[edit] When Completed

That's right!

The answer is just a matter of arithmetic, but you need to be using the right figures. If the time between the front of the train travelling onto the bridge and the back of the train travelling off the bridge is 30 seconds, then the distance travelled in that time is 500m. This means the train travels 1km per minute, which is 60 km per hour.

[edit] Solution


The train is traveling at 60 km per hour.

[edit] Progress

3335 Picarats and 154 Hint Coins.
