Chapter 6: Q30. (page 279)

Write the equivalent rate.
$\frac{15 mi}{1 h} = \frac{? ft}{1 h}$

Short Answer

Expert verified

The equivalent rate of $\frac{15 mi}{1 h}$ is 79200 feet per hour.

Step by step solution

. Given

The given rate is $\frac{15 mi}{1 h}$ .

. To determine

We have to determine the equivalent rate in ft per hour.

. Calculation

In order to find an equivalent rate, we will convert from miles per hour to feet per hour.

For that, we multiply the rate by a conversion factor.

We know that 5280 feet = 1 mile, it means. $\frac{5280 ft}{1 mi} = 1$

$\begin{array}{l} \frac{15 mi}{1 hr} \\ \Rightarrow \frac{15 mi}{1 hr} \times \frac{5280 ft}{1 mi} [Multiplyratebycommonconversionfactor] \\ \Rightarrow \frac{15 mi}{1 hr} \times \frac{5280 ft}{1 mi} [Divideoutcommonfactorandunit] \\ \Rightarrow \frac{79200 ft}{1 hr} [Simplify] \end{array}$ $\begin{array}{l} \frac{15 mi}{1 hr} \\ \Rightarrow \frac{15 mi}{1 hr} \times \frac{5280 ft}{1 mi} [Multiplyratebycommonconversionfactor] \\ \Rightarrow \frac{15 mi}{1 hr} \times \frac{5280 ft}{1 mi} [Divideoutcommonfactorandunit] \\ \Rightarrow \frac{79200 ft}{1 hr} [Simplify] \end{array}$

So, the equivalent rate of $\frac{15 mi}{1 h}$ is 79200 feet per hour.
