You can put this solution on YOUR website! if 4 people can mow a lawn in 1 hour, how many people will it take to mow the same lawn in 45 minutes
----
# of people and amount of time are inversely related:
----
n = k/t
----
solve for "k" using "4 people can mow a lawn in 1 hour"
4 = k/1
k = 4
-----
Equation:
n = 4/t
---
Problem:
how many people will it take to mow the same lawn in 45 minutes
n = 4/(3/4)
n = 16/3
n = 5 1/3 people
Round up to n = 6 people
