Question

It takes 5 minutes for 10 people to drink 25 pints of water. At this rate, how long would it take 15 people to drink 155 pints of water

Answer 1

the time taken for the 15 people to drink 155 pints is 20.67 min.

Explanation:

Given;

10 people took 5 mins to drink 25 pints of water

`The \ rate\ for \ 10 \ people = (25 \ pints )/(5 \ mins) = 5 \ (pints)/(\min) \\\\The \ rate \ for \ 1 \ person = (5)/(10) \ (pints)/(\min) = 0.5 \ (pints)/(\min) \\\\The \ rate \ for \ 15 \ people = 15( 0.5 \ (pints)/(\min) )= 7.5 \ (pints)/(\min) \\\\Time \ taken \ for \ the \ 15 \ people \ to \ drink \ 155 \ pints = (155 \ pints)/(7.5 \ pints/ \min) \\\\= 20.67 \min`

Therefore, the time taken for the 15 people to drink 155 pints is 20.67 min.
