Chapter 6: Q31. (page 279)

Write the equivalent rate.
$\frac{300mi}{20sec} = \frac{? mi}{1 min}$

Short Answer

Expert verified

The equivalent rate of $\frac{300mi}{20sec}$ is 900 miles per minute.

Step by step solution

. Given

The given rate is $\frac{300mi}{20sec}$ .

. To determine

We have to determine the equivalent rate in miles per minute.

. Calculation

In order to find an equivalent rate, we will convert from miles per second to miles per minute.

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

We know that 60 seconds = 1 minutes, it means. $\frac{60 sec}{1 min} = 1$

$\begin{array}{l} \frac{300mi}{20sec} \\ \Rightarrow \frac{300mi}{20sec} \times \frac{60sec}{1 min} [Multiplyratebycommonconversionfactor] \\ \Rightarrow \frac{300mi}{\underset{1}{20} sec} \times \frac{\overset{3}{60} sec}{1 min} [Divideoutcommonfactorandunit] \\ \Rightarrow \frac{900mi}{1 min} [Simplify] \end{array}$

So, the equivalent rate of $\frac{300mi}{20sec}$ is 900 miles per minute.
