Question

Problem: Ms. J’s decided to start a land mowing business, charging a highly discounted rate​. ​Ms. J hired two workers, John and Jason. Jason, being a bit quicker than John, can mow the land 3⁄4 of the time it takes John. One day, they worked on a field together for 2 hours and 16 minutes, and John gave up, whining that it was too hot. Jason continued that it took her an additional 4 hours and 32 minutes to complete the job. How long would it have taken John, assuming he doesn’t make an excuse and quit, if he had mowed all the land alone?

Answer 1

t represents the time John needs working alone

0.75t represents the time Jason needs working alone

For the first 2 hours 16 minutes (76 minutes) they completed

(76 / t) + (76 / 075t)

Then Jason worked for 4 hours 32 minutes (272 minutes) and completed

272 / 0.75t

This totals

(76 / t) + (76 / 075t) + (272 / 0.75t) = 1

Can you solve for t and answer?
