Question

A car is traveling at a speed of 120 kilometers per hour. What is the car's speed in miles per hour? How many miles will the car travel in 4 hours?

Answer 1

The car's speed is 74.5444 mi/hr. It travels 298.2576 miles in 4 hours.

Explanation:

If we want to know the speed in mi/hr, we must convert the km to mi. We can convert from kilometers to miles as follows.

mi = km * 0.62137

Then, if the car is moving at 120 km / hr, we have that the car is moving at

120*0.62137 mi /hr, which is 74.5644 mi/hr. If we want to know how many miles the car travels in four hours, we multiply the speed times the total time. Hence

total distance = 74.5444 mi/hr * 4 hr = 298.2576 miles.
