Question

Student A and Student B are both practicing for a marathon. Student A runs 5 miles every day, while Student B starts running 3 days after Student A and runs 8 miles each day. Define a variable and write an equation that represents the information given. Determine the number of days after Student A starts running when both students will have run the same number of miles.

Answer 1

5(d) = miles student A ran

8(d-3) = miles student B ran

Explanation:

when d = days passed

5(d) = miles student A ran

8(d-3) = miles student B ran
