A man and his son go to a park. Seeing children of his age group, the son starts running and the man also starts running trying to catch him. The man takes 4 paces in the time his son takes 10 paces. The son covers 0.5 m per pace whereas the man covers 1.3 m per pace. How many paces should the man take to catch up with his son who is 9 m ahead?

180 paces?

S = 5 m/s
M = 5.2 m/s
9/0.2 = 45s
=> 45 * 4 = 180

One train is leaving from Delhi to Mumbai at a speed of 85km/hr. At the same time, another train from Mumbai is heading towards Delhi at 100km/hr. A bird is sitting on top of one train before it commutes. When both train starts their journey,fly flies at 125km/hr. And when it meets opposite it reverts its position and flies until it meets first train. This process is continued until it gets crushed between two trains. How much distance the bird travels in whole journey ?
