Question

A construction company needs to remove 10 tons of dirt from a construction site. They can remove 2/5 tons of dirt each hour. How long will take to remove the dirt?

Answer 1

Step-by-step explanation:

You can just divide 10 by 2/5 and you get 25 or try this

Set up proportions and cross multiply 2/5 / 1  =  10/x which you can read as : if 2/5 can be done in 1 hour then 10 tons can be done in x hours cross multiplying, you get 2x/5 = 10  and x = 25
