There is not a way to answer this question. You will have to tell me the rate he was going.
Two and a half laps

It is 2.5 laps/(3+6/60 minutes) = 2.5/3.1 =0.81 laps per minute, approx.
3 laps takes 2.5 minutes → 1 lap takes 2.5/3 minutes → 20 laps take 2.5/3 × 20 minutes = 16⅔ minutes = 16 minutes 40 seconds.
Most high school tracks are 1/4 mile. 20 laps would be 5 miles.
The ratios 4 laps in 1 hour and 32 laps in 8 hours are alike in that both represent a rate of laps completed over time. Specifically, both ratios yield the same rate of 4 laps per hour when simplified. However, they differ in their total quantities; the first ratio has fewer laps and a shorter duration, while the second has more laps and a longer duration, reflecting a higher overall output.
10 minutes
Cooking time for 2.35lbs will be 47 minutes at that rate.
About 10 minutes.
after the same time as you were exercising e.g.(you were exercising for 5 minutes then it will go back after 5 or 4 minutes)
At that rate, 133 minutes.
That depends on your rate of speed. At 60 mph, it will take 16 minutes. At 30 mph, it will take 32 minutes.
