Question

Six students eat 6 apples in 33 seconds. How long will it take nine students to eat 19 apples, if they don't cut apples into parts?

Answer 1

99

Explanation:

It takes each student 33 seconds to eat an apple. This is done in parallel.

The time it would take if each person ate the exact same amount of apples is 69.6 repeating (calculated by (19 * 33) / 9). However, the apples cannot be cut into parts, so we need to round up to the next multiple of 33. Therefore 99 is the answer.

Answer 2

Answer: 104.5 seconds

Explanation:

Hi, to answer this question we have to apply proportions:

Six students eat 6 apples in 33 seconds.

The proportion is: number of apples eaten /time

6 apples /33 seconds = 6/33

For 19 apples:

19 apples / x seconds =19/x

6/33 = 19/x

Solving for x:

x = 19 / ( 6/33)

x = 104.5 seconds
