Exercise 13 Page 270

Use the conversion factor that 1 kilometer is approximately 0.62 mile.

9.3

Practice makes perfect
Let's start by copying the given statement. 15km&≈ mi Converting between kilometers (km) and miles (mi) will involve using a conversion factor. 0.62mi/1km Multiplying 15km by this conversion factor will convert it to miles.
15km* 0.62mi/1km
15km* 0.62mi/1km

Cross out common units

15km* 0.62mi/1km

Cancel out common units

15* 0.62mi/1
9.3mi/1
9.3 mi
To complete the given statement, we will substitute 9.3 into the blank space. 15km&≈ 9.3mi

Common Conversion Factors
The following tool can be used to help you explore some of the most commonly used conversion factors. Conversions can be made both within or between the Metric System and the Imperial System — which is also known as the U.S. Customary System. Conversions can also be made for different measurement types: length, mass, temperature, time, area, or volume.
Conversion factors between different units of measurement
All across the globe, humans use conversion factors on a daily basis. Want to use a recipe that is written using milliliters? Convert it! Want to compare your height to that of an Olympic athlete? Convert it! You can read more about applications of conversion factors in our original content.
