Answer:
The speed of train A is 40 mph and speed of train B is 56 mph
Explanation:
1. Let's review the information given to us to answer the question correctly:
Speed of train A = Speed of train B - 16 mph
Distance of train A = 200 miles
Distance of train B = 280 miles
2. Find the speed of each train.
Let's solve the problem, as follows:
x = Speed of train B
x - 16 = Speed of train A
Like the time in hours is the same for both trains, we can use the Rule of Three Simple this way:
Speed Distance
x - 16 200
x 280
200 * x = 280 * (x - 16)
200x = 280x - 4,480
200x - 280x = - 4,480
-80x = - 4,480
x = -4,480/80
x = 56 ⇒ x - 16 = 40
