Sam decided that he is going to start biking to work as much as possible. after 4 days of work sam has
logged 15 km on his bike.
a. set up a proportion to solve the amount of km he will log after 10 days on the bike.
b. solve for the amount of km in part (a).

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.
