He ACCELERATED the speed of his car.

Veckat went to his collage from his house on his car with a unifrom speed of 60 km h^(-1) and returns to his house with a different speed. If the average speed of the car, for whole journey is 50 km^(h-1) , then find the speed of his car when it travelled from college to house.

By increasing the speed of his car by 15 km/hour, a person covers 300 km distance by taking an hour less than before. The original speed of the car was

Ved travels 600 km to his home partly by train and partly by car. He takes 8 hours if he travels 120 km by train and the rest by car. He takes 20 minutes longer if he travels 200 km by train and the rest by car. Find the speed of the train and the car.

The variation in the speed of a car during it's two hours journey is shown in the fig. The magnitude of maximum acceleration of the car occupies in the interval of

A driver decreases the speed of a car from 25 m/s to 10 m/s is 5 seconds. Find the acceleration of the car.
