Question

Rhonda and Juan ride their bikes in opposite directions: Rhonda at 20 miles per hour and Juan at 15 miles per hour. In 24 minutes, how many miles will they be apart?

Answer 1

14 miles

Explanation:

1 mile = 60 minutes

Rhonda: 20/60=x/24 (put mile per hour equal to mile per hour)

480=60x (cross multiply)

x=8 (solve for x)

Repeat for Juan: 24/60=x/24

360=60x

x=6

6+8=14
