Question

Shen runs each lap in 5 minutes. He will run at most 45 minutes today. What are the possible numbers of laps he will run today? Use n for the number of laps he will run today.

Answer 1

Answer: The possible numbers of laps he will run today = 9

Explanation:

Let
`n` = number of laps he will run today.

Given: Time taken for each lap = 5 minutes

Time taken for
`n` laps =
`5n` minutes

If he runs at most 45 minutes, then

`5n\leq45`

Divide both sides by 5 , we get

`n\leq9`

Hence, the possible numbers of laps he will run today = 9
