The number of minutes Deon will run is equal to or more than 40 minutes if he will run at least 8 laps today.
The possible number of minutes he will run can be determined using inequality.
Inequality is a relation used in mathematics that represents a non-equal comparison between two numbers or any other mathematical expression.
As he runs each lap in 5 minutes and will run at least 8 laps, therefore,
n/5 ≥ 8
Here n represents the number of minutes he will run.
Solving for n;
n ≥ 8 × 5
n ≥ 40
Therefore, the number of minutes he will run is equal to or more than 40 minutes if he will run at least 8 laps today.
