It took mike 2 2/5 hours to drive home. His sister drove same distance in 3/8 of mikes time how long did the drive take mikes sister?

  • Math - ,

    2 2/5 = 12/5

    in these word problems, "of" means "times" as in half of 10 is 1/2 * 10

    So, we have
    3/8 * 12/5 = 36/40

    while that is mathematically correct, it is normal to reduce fractions to lowest terms, by removing common factors from numerator and denominator. So, since

    36/40 = 4*9/4*10 = 4/4 * 9/10,

    and 4/4 = 1,

    we end up with just 9/10.

  • Math - ,

    2 2/5 hours is 132 minutes

    132*3/8 is equal to 45 3/4 minutes

  • Math :-( - ,

    2 1/5 hours is 132 minutes.
    2 2/5 hours is 144 minutes . . .
