    In 3 hours, the cars will be 297 miles apart.

    Explanation:

    Speed=Distance/Time

    Distance = Speed X Time

    Speed of 1st Car=44 miles/hr

    Distance=44 X Time taken = 44t

    Speed of 2nd Car=55 miles/hr

    Distance=55 X Time taken = 55t

    Total Distance Covered by both Cars = 44t + 55t = 99t

    The cars are 297 miles apart, therefore:

    99t = 297

    t = 3 hours

    It means that in 3 hours, the distance between the cars is 297 miles.
