Question

John spent 15 minutes developing an estimate for a job. The job itself took 2 hours, 30 minutes to complete. What is the ratio of the time

spent on the job estimate to the total time spent on this job? Submit answer as #:# or fraction.

Answer 1

Answer: The ratio of the time spent on the job estimate to the total time spent on this job is 1/10. Alternatively, it can also be represented as 1:10

Explanation:

To find the ratio of the time spent on the job estimate to the total time spent on the job, we need to divide the time spent on the estimate by the total time spent on the job, and then express the result as a fraction.

First, we need to convert both times to minutes.

15 minutes for the job estimate

2 hours = 2*60 = 120 minutes

30 minutes

Total time spent on the job = 120 + 30 = 150 minutes

Now we can divide the time spent on the estimate by the total time spent on the job:

15 minutes / 150 minutes = 1/10

So the ratio of the time spent on the job estimate to the total time spent on this job is 1/10. Alternatively, it can also be represented as 1:10
