Answer 13

11.

SInce wade paints a room in 7 hrs, that means that w = 1/7(room/hr)
SInce rhonda paints a room in 5 hrs, that means that r = 1/5(room/hr)

now the amount of time that it will take them to finish a room will be

1/(the rate at which wade works + the rate at which rhonda works)

this will give 2.92 hours
