Currently, the Toyota Corolla is the best selling car in the world. Suppose that during a test drive of two Corollas, one car travels 224 miles in the same time that the second car travels 175 miles. If the speed of the firstvcar is 14 miles per hour faster than the speed of the second car, find the speed of both cars. (Source:Top Ten of Everything)

    its simple ratio
    if
    car A miles car B miles
    224 : 14 :: 175 : y or y

    14:175 :: 224:y
    or 14x175=224xy
    2450=224y
    2450/224=y
    10.9375=y
    or y=10.9375
    or y=11 miles per hour (rounding)

    Note: do the calculation again
