Raphael is timing how fast he can do a series of 5 math questions, aiming to complete them in less than 20 minutes. He has done 3 questions so far, with each of them taking 3

minutes to complete.

On average, how much time does Raphael have on each remaining question so he can reach his goal?
(1 point)

Time left for each question is less than 5.5 minutes

Step-by-step explanation:

Given that:

Raphael is trying to solve 5 math questions in less than 20 minutes.

3 questions have been completed which have taken 3 minutes each.

To find:

How much time is left with Raphael for each question so as to reach his goal.

Solution:

First of all, let us find the time that has been already consumed by Raphael in solving the 3 questions.

3 3 = 9 minutes

Time left = Total Time - Time already consumed

Time left = 20 - 9 = 11 minutes

Number of questions to be solved = Total questions - Questions solved

Number of questions to be solved = 5 - 3 = 2

Average time left for each question = Time left divided by Number of questions to be solved

Average time left for each question = 11 2 = 5.5 minutes

Therefore, time left for each question is less than 5.5 minutes.
