1/4 of a mile and then walked
2/5 of a mile. How many miles did he travel?

1. 1/3 mile
2. 20/13 miles
3. 13/20 mile
4. 3/20 mile

1 answer

To find the total distance Don traveled, we need to add the distance he biked and the distance he walked.

The distance he biked is 1/4 of a mile.

The distance he walked is 2/5 of a mile.

Adding these fractions, we get:

1/4 + 2/5 = (1*5 + 2*4)/(4*5) = 5/20 + 8/20 = 13/20 mile.

Therefore, Don traveled 13/20 mile. So, the correct answer is option 3.
