Question

.

Answer 1

I think the time would be the minutes for her (60) and him (180).
Idk what the work done would be though.

Answer 2

Solve the following for x, the time Samatha takes to do it alone.
1/x + 1/(x/3) = 1/45
The above is read, the whole job in x minutes + the whole job in x/3 minutes has to be to equal the whole job in 45 minutes.

x = 180
x/3 = 60

Sorry, the sigma Equation button is not working at this time.
