Question

John spent 30 minutes developing an estimate for a job. The job itself took 2 hours, 45 minutes to

complete. What is the ratio of the time spent on the job estimate to the total time spent (including the time
spent calculating the estimate) on this job?

Answer 1

Ratio is 11 : 13

Explanation:

We are given;

Time to develop estimate = 30 minutes

Time to do the job = 2 hours 45 minutes = (2 * 60) + 45 = 165 minutes

Total time to develop and do job = 165 + 30 = 195 minutes

Thus;

Ratio of time spent on job to total time = 165 : 195

Whrn this is broken further, we have; 11 : 13
