Question

Tammy runs each lap in 8 minutes. She will run less than 72 minutes today. What are the possible numbers of laps she will run today? Use n for the number of laps she will run today. Write your answer as an inequality solved for n.

Answer 1

Tammy's rate is 8 minutes per lap. If she runs less than 72 minutes, then

$\begin{gathered} 8x<72 \\ x<\frac{72}{8} \\ x<9 \end{gathered}$

Hence, she will run less than 9 laps today.
