<PRE><B>Question 733649</B>
jack took 2 minutes to fill a bucket up.
Sarah took 3 minutes to fill a bucket up.
How long will it take for both of them to fill the same bucket up at the same time?
.
Let x = time (minutes) it takes for both
then
x(1/2 + 1/3) = 1
multiplying both sides by 6 we get:
x(6/2 + 6/3) = 6
x(3 + 2) = 6
x(5) = 6
x = 6/5 minutes
or
x = 1 minute and 12 seconds
