    Proportion:

    4/15 = 20/75

    Sam will bike 37.5 km after 10 days.

    Step-by-step explanation:

    1. Let's review the information given to answer the question correctly.

    Number of days Sam has gone to work biking = 4

    Amount of kilometers Sam has logged on his bike = 15

    2. a. Set up a proportion to solve the amount of km he will log after 10 days on the bike.

    Number of days Sam has gone to work biking = 4

    Amount of kilometers Sam has logged on his bike = 15

    2. a. Set up a proportion to solve the amount of km he will log after 10 days on the bike.

    4/15 = 20/75

    b. Solve for the amount of km in part (a).

    Let's use the proportion, this way:

    20/75 = 10/x

    20x = 75 * 10

    20x = 750

    x = 750/20

    x = 37.5

    Sam will bike 37.5 km after 10 days.
