A car travels at a speed of 120 kilometers per hour. What is the speed of the car in miles per hour? Use the conversion ratio 1 kilometer equals about 0.62 miles.

To convert the speed from kilometers per hour (km/h) to miles per hour (mph), you can use the conversion ratio of 1 kilometer equals approximately 0.62 miles.

Given that the car travels at a speed of 120 km/h, you can calculate the speed in mph as follows:

\[
\text{Speed in mph} = \text{Speed in km/h} \times \text{Conversion factor}
\]

\[
\text{Speed in mph} = 120 \, \text{km/h} \times 0.62 \, \text{miles/km}
\]

\[
\text{Speed in mph} = 120 \times 0.62 = 74.4 \, \text{mph}
\]

Therefore, the speed of the car in miles per hour is approximately **74.4 mph**.
