    Let s = speed of slower airplane Then speed of faster airplane = s + 80 Combined speed = s + s + 80 = 2s + 80 mph Distance = speed * time 2940 = 3(2s + 80) Can you now solve for s?

    i figured it out before but thanks for the effort. While your here, for motion problems it distance divided by rate to find time right
