Question

If Walt can paint 25 feet of fence in an hour, and Joe can paint 35 feet in an hour, how many minutes will it take them to paint a 150foot fence, if they work together?

Answer 1

Together they paint 60 feet in an hour. 30 in half an hour.


60 + 60 + 30 = 150.

So it takes two and a half hour.

Answer 2

Hi, Mahbubamim96! :)

To solve this, we can create a simple equation:
$25x+35x=150$
$x$=the number of hours

Solve for x.
$25x+35x=150$
Add like terms.
$60x=150$
Divide both sides by 60.
$(60x)/60=(150)/60$
$x=2.5$

It would take 2 and a half hours to paint the entirety of the fence.

Hope this helps.
