Question

Anaya swims 10 miles at eachof her practice sessions. how long is a practice session if she swims at an average speed. 2 miles per hour, 2 1/2 miles per hour, m miles per hour, 2 miles per hour more than m miles per hour, three times slower than m miles per hour.

Answer 1

If 2 mph) 5 hours

If 2.5 mph) 4 hours

If m mph) 10/m hours

If m+2 mph) 10/(m+2) hours

If m/3 mph) 30/m hours

Explanation:

To find the time divide the distance (10) by the speed.

10/2=5

10/2.5=4

10/m

10/(m+2)

10/(m/3)=10(3/m)=30/m
