Park rangers at a game preserve in Africa observed a cheetah run 3 3/5 miles in 1/20 hour. What was the cheetahs speed in miles per hour (mph)? A. 9/50 mph
B. 5 5/9 mph
C. 72 mph
D. 92 mph

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
