It takes him 2.4 hours to get to Seattle, driving at 15 miles per hour faster than the speed of the train. Which equation could be used to solve this problem, if t is the speed of the train? A. a. 3(t + 15) = 2.4t

B. b. 3t = 1.4(t - 15)

C. 3(t - 15) = 2.4t

D. 3t = 2.4(t + 15)

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

add 8+12 to get a simplified answer of 12r-20
