Question

Amy planned to run no more than 1 hour. She already has irun for 45 minutes. How many more minutes can she run to stay within her time limit?

Answer 1

If Amy planned to run no more than 1 hour, that means her total time spent running should be less than or equal to 1 hour, or 60 minutes.

having run for 45 minutes already, we can derive the following;

`\begin{gathered} \text{Total time}\leq60\min \\ R\text{emaining time is x, therefore; } \\ 45+x\leq60 \\ \text{Subtract 45 from both sides and you'll have;} \\ 45-45+x\leq60-45 \\ x\leq15 \end{gathered}`

ANSWER:

Amy can still run 15 minutes or less in order to stay within her limit.
