Question

Jack and jill painted one-half of Their bedroom in three-fourths of an hour. At this rate, how long would it take them the paint the entire room

Answer 1

Well they painted HALF the room in 3/4 of an hour.

That means that, considering they keep up the same speed, it will take them 3/4 of an hour to do the OTHER half.

This means that it will take them....

1 and 1/2 hours to do their entire room.

Answer 2

So if they painted 1/2 of the room in 3/4 of an hour ( 45 minutes ) then it would take them another 45 minutes to paint the other half of the room. So 45+45= 90. So 90 minutes, or an hour and a half. Hope this helped! :)
