Run 9

Every time Colin runs, he runs 34 of a mile. Whenever Isabel runs, she runs 14 of a mile. If Colin runs 2 times a week, how many times must Isabel run to cover the same distance as Colin?

Correct answer:

n =  5

Step-by-step explanation:

$$\begin{gathered} 34\cdot 2=14\cdot x \\ 14x=68 \\ x={\displaystyle \frac{34}{7}}\doteq 4.857143 \\ n=[x]=[4.8571]=5 \end{gathered}$$
