Answer:
Step-by-step explanation:
Let m be the number of miles that evelyn can run in 60 minutes.
If evelyn can run 3 miles in 40 minutes, to calculate the number of miles she can run in 60 minutes, we will apply the equality postulate as shown;
3 miles = 40 minutes
m miles = 60 minutes
Cross multiply
40* m = 3* 60
40m = 180
Divide both sides by 40
40m/40 = 180/40
m = 180/40
m = 4.5 miles
The equation that can be used to find m is 40m = 180 and the value of m is 4.5miles
