C 1.17 mi/min
D 0.117 mi/min

The answer is C

Step-by-step explanation:

70 miles            1 hour                   70mh

x           =       = 1.17min

1  hour            60 mh                       60mh

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
