If a car starts from A towards B with some velocity due to some problem in the engine after traveling 30km.If the car goes with 4/5th of its actual velocity the car reaches B 45min later to the actual time. If the car engine fails after traveling 45km, the car reaches the destination B 36min late to the actual time, what is the initial velocity of car and what is the distance between A and B in km ?
(a) 40 & 100
(b) 10 & 150
(c) 20 & 130
1. Let d denote the distance between A and B, v the original speed of the car and t the original traveling time.
