The sum of two trains is 720.2 miles per hour. If the speed of the first train is 9.8 mph faster than that of the second train, find the speeds of each

First train = 365 miles per hour

Second train = 355.2 miles per hour

Step-by-step explanation:

If the speed of the second train is represented by x, then the first train's speed is (x + 9.8)

We can form the following equation:

x + (x + 9.8) = 720.2

2x = 720.2 - 9.8

x = 710.4 / 2

x = 355.2 = speed of second train

Speed of first train = 355.2 + 9.8 = 365
