    Answer:

    7 hours

    Step-by-step explanation:

    The difference in speed of the cars is

    55 mph – 48 mph = 7 mph

    How long does it take for a difference of 7 mph to yield a difference in distance of 49 miles?

    speed = distance/time

    distance = speed * time

    time = distance/speed

    time = 49 miles/7 mph

    time = 7 hours
