This means the train has travelled 135 - 90 = 45 miles in 1 hour.

Therefore the correct answer is A. 45 mph, because speed is the rate of change of distance.

4t+6s=4524
t+s=925

Multiply the second equation by -4 to cancel the variable t
4t+6s=4524
-4t-4s=-3700
2s = 824
Divide both sides by 2
S= 412

925-412= 513
T=513
