Given:

John can finish a paper route in 6 hours and Andrew can finish the same paper route in 5 hours

Required:

We need to find that If they work together how long would it take them to finish the paper route

Step-by-step explanation:

We have that

John can finish a paper route in 6 hours, then he completes 1/6 of paper in 1 hour

similarly

Andrew can finish the same paper route in 5 hours, then he completes 1/5 in 1 hour

Together they complete


(1)/(6)+(1)/(5)=(11)/(30)

11/30 of paper in 1 hour

Therefore, together they need 30/11 hours to finish the paper

FInal answer:


(30)/(11)=2.73\text{ hours}
