A diesel train left Abuja and traveled west. Two hours later a freight train left traveling 15 mph faster in an effort to catch up to it. After six hours the freight train finally caught up. Find the diesel train's average speed. (Need to have chart and explanation)

Step-by-step explanation:

let the speed of diesel train = x

the equation would be:

(2+6)x = 6(x+15)

8x = 6x+90

8x-6x = 90

2x = 90

x = 90/2

x = 45

Therefore, the speed of diesel train =

45 mph
