You can put this solution on YOUR website! It takes 45 min for 2 people to shovel a driveway. How long would it take 5 people to shovel the same driveway?
-----------------------
time and # of people are inversely related.
t = k/#
--------------
Find "k":
45 = k/2
k = 90
---
Equation for your problem: t = 90/#
--------
Your Problem:
t = 90/5
time = 18 minutes
