Answer:To find the average time it takes the athlete to swim the three laps, you need to add up the times for each lap and then divide by the total number of laps.52.45 seconds + 51.75 seconds + 50.51 seconds = 154.71 secondsTo get the average time, divide the total time by the number of laps:Average time = 154.71 seconds / 3 laps ≈ 51.57 secondsTherefore, the average time it takes the athlete to swim the three laps is approximately 51.57 seconds.Step-by-step explanation:Certainly! To calculate the average time it takes the athlete to swim the three laps, we first need to find the total time taken for all three laps. This is done by adding the times taken for each lap together:52.45 seconds (first lap) + 51.75 seconds (second lap) + 50.51 seconds (third lap) = 154.71 secondsNext, to find the average time, we divide the total time by the number of laps, which in this case is 3:Average time = Total time / Number of lapsAverage time = 154.71 seconds / 3 laps ≈ 51.57 secondsTherefore, the average time it takes the athlete to swim the three laps is approximately 51.57 seconds. This calculation gives us an idea of the athlete's overall performance across the three laps.- btw, I hope this answers helps you a lot, but can you heart this or give a some star for me. thanks.
