A company needs to remove 18 tons of dirt from a construction site. They can remove 2/3 tons of dirt each hour. How long will it take to remove the dirt?

Question

None 

Answer 1

you have 18 tons. each single ton = 3/3. so, using sticks as an example : III x18

III III III III III III III III III III III III III III III III III III so, 54 sticks. but they can only take 2 sticks out of the 3 at a time. so, if they only take 2 sticks at a time per hour 54/2= 27 hrs.

Answer 2

Divide the number of tons of dirt by the rate of removal of the dirt.  That will give the time in hours.

 

(18 tons) / (2/3 tons per hour) = ? hours
