The time it takes to clean the beach varies inversely with the number of people picking up garbage. Last year, 34 volunteers took 5 hours to clean the park. If 68 volunteers come to pick up garbage this year, how long will it take to clean the park? It will take approximately hours Question (Simplify your answer.

Solution

let Number of persons be N

Time taken be T

given that time taken is inversely proportional to number of volunteers

==> T 1/N

==> T = k/N (k is proportionality constant)

34 volunteers took 5 hours

==> 5 = k/34

==> k = 34*5

==> k = 170

==> T = 170/N

N = 68

==> T = 170/68

==> T = 5/2

==> T = 2.5

Hence it takes 2.5 hours (i.e, 2 hours 30 min) for 68 volunteers to clean the park.
