Final answer:
By dividing the total time Steve runs 5 laps (12 minutes) by the number of laps (5), we find that it takes Steve 2.4 minutes to run 1 lap.
Step-by-step explanation:
To calculate the time Steve takes to run 1 lap, we need to divide the total time by the number of laps. He runs 5 laps in 12 minutes, so we can calculate the time per lap as follows:
Time per lap = Total time / Number of laps
Time per lap = 12 minutes / 5 laps = 2.4 minutes per lap
So the answer is (a) 2.4 minutes.
