Problema Solution
It takes Gary 1 h to milk all of the cows, and it takes Dana 1.5 h. How long will it take them to do the job together?
Answer provided by our tutors
We assume the time working together is t, so the equation is below:
1/t = 1/1 + 1/1.5
We solve this
t = 0.6
So it takes 0.6h if working together
