Question

A) 2 laps
B) 3 laps
C) 4 laps
D) 1 lap

Answer 1

Maria can run 2 laps in 2 minutes, calculated by finding her rate per minute and multiplying by 2 minutes. The correct answer is A) 2 laps.

Step-by-step explanation:

Maria runs 3 laps in 3 1/3 minutes. To find out how far she can run in 2 minutes, we first need to find her running rate per minute. Here is the step-by-step calculation:

1. Convert 3 1/3 minutes to an improper fraction: 3 1/3 = 10/3 minutes.
2. Divide the number of laps by the total time to get the rate: 3 laps ÷ (10/3) minutes = 3 laps ÷ 10/3 minutes = 9/10 laps per minute.
3. Multiply this rate by 2 minutes to find out how many laps she can run in 2 minutes: (9/10 laps per minute) × 2 minutes = 18/10 laps = 1.8 laps.

Since the options are whole numbers, we round 1.8 laps to the nearest whole number, which gives us 2 laps. Therefore, the answer is A) 2 laps.
