summer can paint a room in 3 hours. Louise can paint the room in 5 hours. How many hours will it take them to paint the room if they work together
Answer provided by our tutors
Let x represent the time it takes together. Per hour the Equalizer
1/3hr + 1/5hr = 1/x
Multiplying each term by 15x so as all denominators = 1
5x+3x = 15
8x = 15
x = 15/8 or 1.875 hrs, the time it takes them together
