Given: Distance = speed * time

If the car's average speed is 100 km/h, in 3 hours distance will be:

100 * 3 = 300 km

To cover 300 km in 2 hours, the required average speed, given speed = Distance/Time:

300/2 = 150 km/h

The car must travel at an average speed of 150 km/h to cover that distance in 2 hours.
