Answer:

Number of minutes per lap = 2.25 minute

Number of lap per minute = 0.444 lap (Approx)

Time taken for 15 lap = 33.75 minutes

Step-by-step explanation:

Given:

Number of laps = 4

Time taken = 9 min

Computation:

Number of minutes per lap = 9 / 4

Number of minutes per lap = 2.25 minute

Number of lap per minute = 4 / 9

Number of lap per minute = 0.444 lap (Approx)

Time taken for 15 lap = 15 x 2.25

Time taken for 15 lap = 33.75 minutes
