A train passes two persons walking in the same direction in which the train is going, at the speeds of 2 km/hr and 4 km/hr, in 9 seconds and 10 seconds respectively. Find the length of the train.
The relative speed with respect to the first person = (Speed of train – 2) km/hr. Since speed = distance/time, the length of the train = (Speed of train – 2) * 5/18 * 9 meters. Similarly, with respect to the second person, length = (Speed of train – 4) * 5/18 * 10 meters. Equating both and solving gives the length of the train ≈ 55 meters.

In a 100 meter race, A runs at 5 m/s and B at 4 m/s. If A gives B a start of 20 meters, how far from the finishing line will A overtake B?
When A reaches the finishing line, B has run 100 – 20 = 80 meters. The time taken by A to finish the race = 100/5 = 20 seconds. In 20 seconds, B runs 20 * 4 = 80 meters. So, A overtakes B 20 meters from the finishing line.

A rectangular park 60 m long and 40 m wide has two roads, each 5 m wide, running in the middle of it, one parallel to the length and the other parallel to the breadth. Find the area covered by the roads.
