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 3 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

Answer 1

The car's speed of 120 kilometers per hour is equivalent to 75 miles per hour. In 3 hours, at this constant speed, the car will cover a distance of 225 miles.

Step-by-step explanation:

To convert the car's speed from kilometers per hour to miles per hour, we use the given conversion factor: 1 mile = 1.6 kilometers.

Starting with the car's speed:

• 120 km/h ÷ 1.6 km/mi = 75 mi/h

Therefore, the car's speed is 75 miles per hour. Now, to calculate how many miles the car will travel in 3 hours at this constant speed:

• 75 mi/h × 3 h = 225 miles

So, in 3 hours, the car will travel 225 miles.
