On a standardized test, Paul answered the first 22 questions in 5 minutes. There are 77 questions on the test.

If he continues to answer questions at the same rate, how long will it take him to complete the test

from start to finish?

Answer: time it will take him to 17.5 minutes to complete the test from start to finish

Step-by-step explanation:

During the standardized test, Paul answered the first 22 questions in 5 minutes.

If he answers 22 questions 5 minutes

He would answer one question in 5/22 = 0.227 minutes

He continues to answer questions at the same rate. This means that his unit rate of answering 1 question in 0.227 minutes is constant throughout the test.

Total number of questions on the test is 77. The time it will take him to complete the test from start to finish will be

Unit rate of answering questions * total number of questions

= 0.227 * 77 = 17.5 minutes

17 minutes 30 seconds homie
