A car decreases its speed from 80 km/hr to 60 km/hr in 5 seconds. The acceleration of the car is :
A car travels at a speed of 60 km/hr. Write the distance – time formula and draw the graph of it. Also, find the distance travelled by the car in 5 hours.
By increasing the speed of a car by 10km/hr, the time of journey for a distance of 72km is reduced by 36mins. Find the original speed.
