Chapter SH, Problem 4RAP

Solution

To write the ratio $375\text{ mi in }4.3\text{h}$ in simplest form.

  $87.21\text{ mi}/\text{h}$

Given:

The ratio, $375\text{ mi in }4.3\text{h}$ .

Concept Used:

The ratio of two numbers is obtained by dividing the first number by the second number.

Calculation:

In order to write the ratio $375\text{ mi in }4.3\text{h}$ into simplest form, divide the first number by the second number and reduce the fraction in simplest form by cancelling out the common factors from both numbers as shown below

  $\begin{array}{c}375\text{ mi in }4.3\text{h}=\frac{375\text{ mi}}{4.3\text{h}}\\ =\frac{87.21\text{ mi}}{1\text{h}}\\ =87.21\text{ mi}/\text{h}\end{array}$

Thus, the give ratio in simplified form can be expressed as $87.21\text{ mi}/\text{h}$ .
