Answer:
Bella can complete work alone in 120 minutes
Step-by-step explanation:
Ana and Bella together can complete the shoveling in 30 minutes.
They can do a part of work in 1 minute = ![\frac{1}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B30%7D)
Ana can do work alone in 40 minutes
She can do part of work in 1 minute = ![\frac{1}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B40%7D)
So, Bella can do a part of work in 1 minute = ![\frac{1}{30}-\frac{1}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B30%7D-%5Cfrac%7B1%7D%7B40%7D)
= ![\frac{1}{120}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B120%7D)
Bella can do
part of work in 1 minute
Bella can do whole work in minutes = 120
Hence Bella can complete work alone in 120 minutes
