Question

A car is traveling at a speed of 70 kilometers per hour. What is the car's speed in miles per hour? How many miles will the car travel in 5 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.

Answer 1

What is the car's speed in miles per hour?

Let's make a conversion:

How many miles will the car travel in 5 hours?

1h---------------------->43.75mi

5h---------------------> x mi

`\begin{gathered} (1)/(5)=(43.75)/(x) \\ x=5*43.75 \\ x=218.75mi \end{gathered}`
