Answer 5

the problems boil down to finding how much work each can do in 1 hour (min, sec, week, etc) and then adding them together to find out the total that can be done in 1 hour

Answer 6

I got 30/11, but that can't be the right answer. It must be 2 hours and something...

Answer 7

.... if only there was a way to convert 30/11 into some sort of mixed system of numbers lol

Answer 8

it is
\[\frac{30}{11}\] now convert to a mixed number. 11 goes in to 30 twice, with a remainder of 8, so the mixed number is
\[2\tfrac{8}{11}\]

Answer 9

ahhhh
