    1. If Bob gets 10 apples per 2 milk carton, Bob would have 4 milk cartons if he gets 20 apples. I got this answer by multiplying 10 apples and 2 milk cartons by 2 (10 apples x 2 = 20 apples and 2 milk cartons x 2 = 4 milk cartons)

    1. If Matthew is driving 75 km/h, it will take him 1.86 hours to reach 140 km. I used cross product to figure out the answer. I divided 75 and 140 by 75.
