Question

Ravish drives a car at the speed of 60 km/hr to reach a place in 6 h. If he drives the car at a speed of 45 km/h, how long would it take for him to travel the same distance? with proper statements​

Answer 1

Answer:

Assuming that the speed of the car is constant and does not drops or accelerates from 60km/hr, it took him 4 hours to reach the destination, hence the destination is 60x4=240kms away. Speed x Time =Distance. Now with the same logic, to cover the Distance(D) of 240 kms in Time(T) of 3 hours, he will need to drive at the Speed(S) of => D/T=S,i.e. 80km/hr.

Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. ... In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).
