Question

1. Addie, Namanda, and Taylor can paint a room together in 6 hours. If Addie and Namanda could do it in 10 hours, how long would it take Taylor by herself?​

Answer 1

Answer:

15 hours

Step-by-step explanation:

A+N=10

(1/A+N)=1/10

(1/A+N) + (1/T)= 1/6

1/T= 1/6-1/10

1/T= (5-3)/30 = 2/30 = 15
