To find the time it takes for the car to reach City B, we can use the formula:
Time=DistanceSpeedTime=SpeedDistance
Given that the distance from City A to City B is 300 kilometers and the average speed of the car is 60 kilometers per hour, we can substitute these values into the formula:
Time=300 km60 km/hrTime=60 km/hr300 km
Time=5 hoursTime=5 hours
So, it takes the car 5 hours to reach City B.
