Question Notes On Time, Speed And Distance
Time, Speed and Distance
1. If a car starts from A towards B with some velocity. Due to some problem in the engine after traveling 30km, the car goes with (4/5)th of its actual velocity. The car reaches B 45 minutes later than the actual time. If the car engine had failed after traveling 45km more, the car would have reached the destination (B) 36minutes later than the actual time. What is the initial velocity of the car in km/hr? (a) 60 (b) 77 (c) 75 (d) None of these 2. A and B are two places, while C and D are two people. C started from A and D started from B. When they meet each other on the way C had travelled 18m more than D. Then C takes 16 minutes and D takes 24 minutes to reach the other end. What was the distance between …show more content…
