Question

PLEASE ANSWER QUICK I NEED TO FINISH IN 50 MINUTES FOR MY TEST

James and Willis are both painting a room. James could complete it in 6 hours by himself. Together they can complete the room in 2 hours. How long would it take Willis to paint the room by himself?

Answer 1

Answer: Willis will take 3 hours to paint the room by himself.

Explanation:

Given: Time taken by James to complete job by himself = 6 hours

Let Time taken by Willis to complete job by himself = t hours

Together they take 2 hours.

`(1)/(6)+(1)/(t)=(1)/(2)\\\\\Rightarrow\ (1)/(t)=(1)/(2)-(1)/(6)\\\\\Rightarrow\ (1)/(t)=(3-1)/(6)\\\\\Rightarrow\ (1)/(t)=(2)/(6)\\\\\Rightarrow\ t=(6)/(2)\\\\\Rightarrow\ t=3`

So, Willis will take 3 hours to paint the room by himself.
