Trent can deliver his newspapers in 40 minutes. it takes lois 60 minutes to do the same route. how long would it take them to deliver the newspapers if they work together?

The correct answer is 24 minutes

Step-by-step explanation:

Given.

Trent deliver in 40 minutes

Lois deliver in 60 minutes

We can calculate this problem in the next way:

(1/40 + 1/60) x = 1

first we have to expand the fractions first with 3 and the other with 2

and get

(3/120 + 2/120) x = 1  => (5 / 120) x = 1 => x = 1 : (5 / 120) = 1 · 120/5 = 24

x = 24 minutes
