    Step-by-step explanation:

    add up their speed.

    combined speed = x + 1 x + 10

    (2 x + 10)

    Time = 5 hours

    Distance = 750 miles

    Distance = speed * time

    (2 x 10) * 5 = 750

    10 x + 50 = 750

    10 x = 750 + - 50

    10 x = 700

    / 10

    x = 70 mph Car A

    Car B 70 + 10 = 80 mph
