Elle can type a manuscript in
3 hours while Mimi can type the same manuscript in  5 hours. How long will it take them to
type the manuscript if they work together?








Sagot :

since Elle can do the job for 3 hours then you'll have the rate as 1/3
        Mimi can do it for 5 hours then the rate is 1/5
to get the number of hours you'll have the equation:
rate x time = work
let 't' be the number of hours
1/3t + 1/5t = 1
8/15t = 1
t = 15/8 or 1.875hrs
Elle and Mimi will take three hours to type the manuscript.
