George can mow his lawn in 3 hours, Al can mow his lawn in 5 hours.
How long will it take both of them working together?

Step-by-step explanation:

so let put into fraction

george=⅓

Al=1/5

so ⅓+1/5=8/15 (as both denominator will be 15 by X5 and X3)

We want to know how many hours they have to mow in order to mow 1 lawn.

This can be represented by the equation: (8/15)*x=1

To solve for x, we would divide both sides by 8/15. This leaves us with x=15/8 which is 1.875.

If you would like this answer in hours and minutes, covert the .875 to minutes by multiplying by 60.

This gives you a final answer of about 1 hour and 53 minutes.

if this is really you s much. i only have 3 points left and i have 2 questions to ask
