Question

mai runs each lap in 5 minutes. she will run less than 45 minutes today what are the possible numbers of laps she will run today. write it as a inequality and use n for the number of laps she will run today​

Answer 1

The possible numbers of laps Mai will run today are any number less than 9.

Step-by-step explanation:

To find the possible numbers of laps Mai will run today, we need to divide the total time she will run by the time it takes to run each lap.

Since Mai wants to run less than 45 minutes, we can write the inequality as: 5n < 45, where n represents the number of laps she will run.

To solve for n, we divide both sides of the inequality by 5 and simplify: n < 9.

Therefore, the possible numbers of laps she will run today are any number less than 9.

Answer 2

The possible number of laps are :
`1,2,3,4,5,6,7\ and\ 8`

Step-by-step explanation:

Given:

Time taken by Mai to run each lap = 5 minutes

Total number of laps =
`n`

Tie taken to run
`n` laps =
`5n` minutes.

Mai runs less than 45 minutes.

So, we have
`5n<45`

We solve for
`n`

Dividing both side by 5.

`(5n)/(5)<(45)/(5)`

`n<9`

Therefore number of laps is less than 9.

So, the possible number of laps are :
`1,2,3,4,5,6,7\ and\ 8`
