Two trains one of 100 meter size with an hourly speed of 100 km and the other of 200 meters with a speed of 30 per hour start from one station at a time on two parallel lines in the same direction. How long will it take to cross the slower train by the faster train?

Since this is a homework problem you need to show us what you've been able to do. We are not a homework service and help on a graded assignment is cheating. We can help you, but you'll only get a hint or two.
