Question

It takes James 16 hours to harvest the field. Nick can harvest the same field in 10 hours. If they work together how long will it take them?

Answer 1

26 hours hope this helps

Answer 2

Answer is 80/13 = 6.15 hrs

(1/16)x + (1/10)x = 1
(5/80)x + (8/80)x = 1
(13/80)x = 1
x = 80/13 = 6.15 hrs
