Answer:

Adam's average speed is 42 mph

Explanation:

Let Adam's average speed be x

Krystal travelled 28 mph faster than Adam

Therefore, Krystal's average speed is (x + 28) mph

Krystal left 2 hours after Adam and caught up with him after 3 hours

Total time taken for Adam to travel a distance d m = 2 hours + 3 hours = 5 hours

Time taken for Krystal to travel the same distance (catch up with him) = 3 hours

Average speed = distance/time

distance = average speed × time

Since both travelled the same distance

5(x) = 3(x+28)

5x = 3x + 84

5x - 3x = 84

2x = 84

x = 84/2 = 42 mph

Adam's average speed is 42 mph
