a. Lin runs 1.2 minutes per lap.
b. Lin runs approximately 0.833 laps per minute.
c. Running 21 laps takes Lin roughly 25.2 minutes.
Let's break this down step by step:
a. To find out how many minutes per lap Lin runs, you can divide the total time by the number of laps:
Minutes per lap= Total time/ Number of laps = 6 minutes/ 5 laps =1.2 minutes per lap
b. To determine how many laps Lin runs per minute, you can take the reciprocal of the previous result:
Laps per minute= 1/ Minutes per lap = 1/ 1.2 minutes per lap ≈0.833 laps per minute
c. If Lin runs 21 laps at the same rate, we can use the information about her laps per minute to calculate the time it will take her:
Time taken= Number of laps/ Laps per minute = 21 laps/ 0.833 laps per minute ≈25.2 minutes
So, if Lin runs 21 laps at the same rate, it would take her approximately 25.2 minutes.
