Final answer:
To calculate the minutes per lap for Lin, divide the total time of 15 minutes by the 5 laps she ran. The result is 3 minutes per lap.
Step-by-step explanation:
The student has asked how many minutes per lap it takes for Lin to run 5 laps around a track in 15 minutes. To find the minutes per lap, we simply divide the total time taken by the number of laps completed. Here’s a step-by-step solution:
- Start with the total time spent running, which is 15 minutes.
- Divide the total time by the number of laps, which is 5 laps.
- The calculation is: 15 minutes ÷ 5 laps = 3 minutes per lap.
This means that Lin runs each lap in 3 minutes. This is an example of a simple division problem in mathematics where the units of measure (minutes and laps) help to find the rate.
