1 lap is 400 metres. 5 mins 11 sec is 311 sec. 311/1500x400 is 82.933 seconds or 1 min 23 seconds
1.25 seconds.
1.50 minutes per lap. But you could get a 2.55 on your first 800 meters then a 3.00 on your second and you will have a 5.55 mile! or you can adjust your times to get 6.00 minutes.
88 seconds
To calculate the time it takes to complete 18 laps in 6 minutes, you would divide the total time by the number of laps. In this case, 6 minutes divided by 18 laps equals 0.33 minutes per lap. To convert this to seconds per lap, you would multiply by 60, resulting in 20 seconds per lap.

Assuming that it took Marty 15% longer than the third lap to walk the 4th lap, it will have taken Marty 6.9 minutes to walk the 4th lap, for a grand total of 21.9 minutes to walk all 4. (4*1.25=5; 5*1.2=6; 6*1.15=6.9; 4+5+6+6.9=21.9). lap 1 = 4 minutes lap 2 = 4minutes x 1.25 = 5 minutes lap 3 = 5 minutes x 1.20 = 6 minutes lap 4 = 6 minutes x 1.15 = 54 seconds total time = 21 minutes 54 seconds. Both answers are correct. I was not able to view all of the question the first time I read it.
if someone does a lap every four minutes another person does a lap in five minutes and one more person does a lap in six minutes when will they all meet
12 minutes
Run 90 seconds per lap. More realistically, your first lap should probably be under 85 seconds, try to keep your first two laps under 3 minutes, don't slow down or get discouraged in your third lap, and give it all you've got in the last lap, especially the last 100 meters.
