Final answer:
To calculate the time it takes Sarah to run 4 laps, multiply the time for one lap (3.6 minutes) by 4. Sarah will take 14.4 minutes to run 4 laps.
Step-by-step explanation:
If Sarah can run a lap around the track in 3.6 minutes, to solve the mathematical problem completely and determine how long it will take her to run 4 laps, you would perform a simple multiplication of the time it takes to run one lap by the number of laps.
Here's the calculation:
- Time to run 1 lap = 3.6 minutes.
- Time to run 4 laps = 3.6 minutes/lap × 4 laps.
- Time to run 4 laps = 14.4 minutes.
Therefore, it will take Sarah a total of 14.4 minutes to run 4 laps around the track.
