Answer to Problem 26SP

The number of blocks walked in 48 minutes is $\text{24}\text{blocks}$ .

Explanation of Solution

Given information:

It is known that $1\text{mile}\text{=}\text{10}\text{blocks}$ and $\text{1}\text{mile}\text{= 20}\text{mins}$ .

The methods for solving numerical problems are arranged into a three-step approach to problem-solving.

Analyzing, calculating, and evaluating are the steps in solving a numerical word problem.

The number of blocks traveled in 48 minutes is given as:

  $\begin{array}{c}\text{blocks}\text{=}\text{48}\cancel{\text{mins}}\text{×}\frac{\text{1}\cancel{\text{mile}}}{\text{20}\cancel{\text{mins}}}\text{×}\frac{\text{10}\text{blocks}}{\text{1}\cancel{\text{mile}}}\\ \text{=}\text{24}\text{blocks}\end{array}$

The number of blocks walked in 48 minutes is $\text{24}\text{blocks}$ .
