    Answer:

    The time it will take Kalin will be 2h 33m

    Step-by-step explanation:

    First we will transform the numbers to work more comfortable

    d = distance

    v = velocity

    v = 3 2/3 miles per hour = 3.33 mi/h

    d = 4 1/4 milles = 4.25 mi

    As the time it takes to go to the beach and back asks us, we have to do the distance 2 times

    d = 4.25 mi * 2

    d = 8.5 mi

    To calculate the time it takes, we simply have to divide the distance by the velocity

    t = d/v

    t = 8.5 (mi) / 3.33(mi/h)

    t = 2.55h

    if we also want to express the minutes we can divide after the point .55 by 100 and multiply it by 60

    (55/100)*60 = 33

    t = 2h 33m

    The time it will take Kalin will be 2h 33m
