Answer
24 blocks
Work Step by Step
We know the distance to be traveled=8 blocks
walking speed= 1 mile/20 minutes
1 mile= 10 blocks
First, we need to determine how many miles can be walked in 48 minutes
48 minutes$\times$ (1 mile/20 minutes)=2.4 miles
Now we need to convert miles to blocks
2.4 miles$\times$(10 blocks/1 mile)=24 blocks
