Question

wilde oscar worked frantically for 4 hours and called for help because he saw it would take 6 more hours to finish. calm sally began to help and they finished the job in 2 more hours. how long would it have taken sally to do the job alone, putting your answer in fractional form?

Answer 1

In fractional form, the time it would have taken Sally to do the job alone is 1/3.

We know that Oscar worked for 4 hours, and they worked together for an additional 2 hours, for a total of 4 + 2 = 6 hours.

We know that he worked for 4 hours, and the fraction of the job completed per hour is 1, so he completed 1 * 4 = 4/6 of the job. The fraction left for Sally will be:

= 1 - 4/6

= 1/3

This means that Sally completed the remaining 2/6 of the job. In fractional form, the time it would have taken Sally to do the job alone is 1/3.
