    Answer: the rate of the slower car is 93 kilometers per hour.

    Step-by-step explanation:

    Two cars leave towns 1000 kilometers apart at the same time and travel toward each other. This means that by the time they meet, they would have travelled a total distance of 1000 kilometers.

    Let x represent the rate of the slower car. One car's rate is 14 kilometers per hour less than the other's. This means that the rate of the faster car is (x + 14) km/h

    Distance = speed * time

    If they meet in 5 hours, then the distance covered by the slower car is 5x kilometers.

    Also, after 5 hours, the distance covered by the faster car is 5 (x + 14) kilometers.

    Since the total distance covered is 1000 kilometers, then

    5x + 5 (x + 14) = 1000

    5x + 5x + 70 = 1000

    10x = 1000 - 70

    10x = 930

    x = 930/10

    x = 93
