1. David worked 7 1/3 hours today and planted || trees. It takes him about the same amount of time to plant each tree. How long did it take him to plant each tree? It took him _____ hour to plant each tree.

Answer 1

For this problem we know that David worked 7 173 hours today and planted 11 trees. And we want to find How long did it take him to plant each tree?

So we can set up the following equation:

`(11\cdot3)/(22)=(x)/(1)`

And solving for x we got:

`x=1.5\text{ hr}`

It took him 1.5 hour to plant each tree.
