Answer to Problem 25SP

The minutes will it take to walk there and back is $24\text{mins}$ .

Explanation of Solution

Given information:

There are six blocks from the ice cream shop to the hotel.

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.

There are six blocks from the ice cream shop to the hotel.

To travel from the hotel to the ice cream shop and come back to the hotel, there are a total of 12 blocks.

To calculate the time to travel from the hotel to the ice cream shop and come back, follow the calculation below:

  $\begin{array}{c}\text{time}\text{=}\text{12}\cancel{\text{blocks}}\text{×}\frac{\text{1}\cancel{\text{mile}}}{\text{10}\cancel{\text{blocks}}}\text{×}\frac{\text{20}\text{mins}}{\text{1}\cancel{\text{mile}}}\\ =24\text{mins}\end{array}$

The minutes will it take to walk there and back is $24\text{mins}$ .
