A car travelled at an average speed of 72 km per hour how many km does it cover in 4.5hrs
To find the distance covered by the car, we can multiply the average speed of the car (72 km/h) by the time traveled (4.5 hours):
Distance = Speed x Time
Distance = 72 km/h x 4.5 h
Distance = 324 km
Therefore, the car covers 324 km in 4.5 hours.
