Two workers work equally efficiently and together can complete a given task in 5 hours. One worker improved his machine, changed his workflow, and increased his output by 40%. How long will it take both workers to complete the given task?

Correct answer:

t =  4.1667 h

Step-by-step explanation:

 1 = 5/a + 5/a 10/a = 1 a=10  r=100%+40%=1+10040=1.4  b=a/r=10/1.4=7507.1429  t (1/a+1/b)=1 t (1/10+1/7.1428571428571)=1  2.4t=10  t=2.410=4.16666667  t=6254.166667=4.1667 h
