An athlete runs 8 miles in 50 minutes on a treadmill. At this rate:

a. How long will it take the athlete to run 9 miles?

b. How far can the athlete run in 1 hour?

a 56.25 minutes

b 9.6 miles

Step-by-step explanation:

To find the rate, we take the miles and divide by the minutes

rate = 8 miles / 50 minutes

.16 miles per minute

A. how long to run 9 miles

We want to use the formula

d = rt where d is the distance, rate is the rate and t is the time

9 =.16 * t

Divide each side by. 16

9/.16 =.16/16 * t

56.25 = t

It will take 56.25 minutes

B We have a time of 1 hour

We want to use the formula

d = rt where d is the distance, rate is the rate and t is the time

t = 1 hour, but our rate is in minutes

1 hour = 60 minutes so t = 60 minutes

d =.16 * 60

d = 9.6 miles
