Answer 2

Concept introduction:

We have been given time in fraction in hours so we have to convert it into minutes. $1hr = 60 minutes$.

Explanation:

Given that, Jaspreet, Kiran and third person community swimming pool. They take two-thirds of an hour, five-sixths of an hour and four-fifths of an hour, respectively

We have to find, who takes the least time to complete a lap.

According to the question,

Time taken by Jaspreet = $2/3hr=40min$

Kiran = $5/6hr=50min$

Third person = $4/5hr=48min$

Therefore Jaspreet takes least time.

Final Answer:

Jaspreet completes the lap first.
