Trent can deliver his newspapers in 10 minutes. It takes Lois 40 minutes to do the same route. How long would it take them to deliver the newspapers if they worked together

It will take them 8 minutes to work together

Step-by-step explanation:

Trent: 10 minutes = 1/10

Lois: 40 minutes = 1/40

Together: x minutes = 1/x

1/10(10x) + 1/40(10x) = 1/x(10x) --> x + 1/4x = 10 --> 5/4x = 10

10/1 divided by 5/4x = 10 times 4 divided by 5 = 8 minutes

is this part of a question or something

step-by-step explanation:

mean or average is 40.6
