Question

Trent can deliver his paper route in 40 minutes, Lois can deliver the same route in 60 minutes. How long will it take if they work together?

Answer 1

I think it will take 50 minutes because it is in the middle of 40 and 60

Answer 2

Together they will take;

`(1)/(40) + (1)/(60)`
=
`(3+2)/(120)`
The find reciprocal,
=
`(120)/(5)`
=24 minutes
