Question

rafael runs each lap in 7 minutes. he will run at least 12 laps today. what are the possible numbers of minutes he will run today? use t for the number of minutes he will run today. write your answer as an inequality solved for t.

Explanation:

Step1: Define the relationship

Each lap takes 7 minutes, and the number of laps is at least 12. Let \( t \) be the total minutes. The number of laps is \( \frac{t}{7} \), and this is at least 12. So the inequality is \( \frac{t}{7} \geq 12 \).

Step2: Solve the inequality

Multiply both sides by 7: \( t \geq 12\times7 \). Calculate \( 12\times7 = 84 \), so \( t \geq 84 \).

Answer:

\( t \geq 84 \)
