3 cars leave Patna for Ranchi after equal time intervals . They reach Ranchi simultaneously and then leave for Vizag, which is 120 kms from Ranchi. The first car arrives there an hour after the second car, and the third car, having reached Vizag , immediately reverses the direction and 40 km from Vizag meets the first car. Find the speed of the first car.

Three sprinters A, B and C had to sprint from points P to Q and back again (starting in that order). The time interval between their staring times of the three sprinters was 5 seconds each. Thus C started 10 seconds after A,while B started 5 seconds after A. The three sprinters passed a certain point R, which is somewhere between P and Q, simultaneously (none of them having reached Q yet). Having reached Q and reversed the direction, the third sprinter met the second one 9 m short of Q and met the first sprinter 15m short of Q. Find the speed of the first sprinter if the distance between PQ is equal to 55 m?
