Answer: 112.5 hours

Concept: Time and work

Given: Susan and Kate while working together can complete a piece of work in 50 hours

To Find: Time taken by Susan to complete the work

Step-by-step explanation:

Susan and Kate working together can complete a work in 50 hours.

∴ In one hour they can complete 1/50​th of work

Kate can alone do the work in 90hr

∴ In one hour A can complete 1/90​th of work.

Let’s suppose in one hour Susan can do 1/x​th of work

1/90+1/x= 1/50

1/x= 1/50-1/90

1/x= 9-4/450

1/x=5/450

x=450/5

x=112.5

Thus, Susan can complete the work in 112.5 hours.
