A Jogger has attempted to run across a railroad bridge, but sees a train coming after completing 3/4 of the trip. Question below?
If the train is traveling at 30 km/h, and if it is possible for the jogger to just escape being hit by the train by running at full speed to either end of the bridge, what is the minimum speed, in km/h, that this jogger must be able to run?

To know that you'd need to know how far away the train was, and the length of the bridge!

It depends which direction the train is coming from and where it is when he sees it. I would advise him to jump and not worry about the maths.
