If a car travels 120 miles in 2 hours, how far will it travel in 3 hours at the same speed?

Explanation

A car travels 120 km in 2 hours

Then the distance traveled by the car in 1 hour = 120/2km 

=60km

Then the distance travelled by the car in 3 hours= 3*60km

=180km

Hence the car travels 180km in 3 hours
