    First you need to find the rate. This problem is based on the formula d = rt

    d = distance

    r = rate

    t = time.

    The question is asking how many miles will it travel in 8 hours so to find this out we need to find the rate when the car travels 240 miles in 4 hours. We use this information and plug it into the model d = rt

    d = 240

    r = don't know yet

    t = 4 hr

    d = rt

    240 = 4r

    240 / 4 = 4r / 4

    60 = r

    r = 60

    So the car is going at a rate of 60 miles per hour. Now that we know this we can solve for how many miles the car will travel in 8 hours.

    d = rt

    d = r * t

    d = 60 * 8

    d = 480

    So the car will travel 480 miles in 8 hours

    Another way to think about this is that you know the car traveled 240 miles in 4 hours and the question is wanting to know how far the car will travel in 8 hours, which would be double the 4 hours so 240 + 240 = 480
