Answer
12 Minutes
Work Step by Step
First, we have our known information
distance to be traveled=8 blocks
walking a speed=1 mile/per 20 minutes
1 mile= 10 blocks
To calculate our first step is to convert blocks to miles
6 blocks\times(1 mile\10 blocks)= 0.6 mile
Then we must convert miles to minutes
0.6-mile times (20 minutes/1 mile)= 12 minutes
12 minutes in the answer
