Question

Jeremy can row 2/3 of a mile in 1/2 hour how long will it take him to row 1 mile?

2 Answer

  • Answer:

    4/3

    Step-by-step explanation:

    2/3 = 1/2

    1 = x

    (2/3)x / (1/2) = x * 2/3 * 2/1 = x * 4/3 = 4/3x

    2/3 = 1/2

    1 = 4/3

    tell me if I'm wrong I'm not 100% sure...

  • Answer:

    It takes 3/4 of an hour to go 1 mile

    Step-by-step explanation:

    You can do this by setting up a proportion and by using decimals for some fractions

    2/3 = 0.66667 Miles

    1/2 = 0.5  hours

    0.66667/0.5 = 1/x                         Cross multiply

    0.66667 * x = 0.5 * 1                     Simplify

    0.66667 * x = 0.5                         Divide both sides by 0.66667

    x = 0.5 / 0.66667

    x =  0.74999625                           Notice when rounded this is 0.75

    x = 0.75                                         Now notice that 0.75 as a fraction is 3/4

    x = 3/4
