Answer 2

Answer:

Speed of train 1 = 355.8 miles per hour,

Speed of train 2 = 362 miles per hour

Step-by-step explanation:

Let's say the speed of the first train is x

Speed of train 1 = x,

Speed of train 2 = x + 6.2

If the sum of the both speeds are 717.8 miles per hour, the set up should be as follows;

x + (x + 6.2) = 717.8

2x = 711.6,

x = 711.6/2 = 355.8 miles per hour (first train)

355.8 + 6.2 = 362 miles per hour (second train)
