Question

Working together Manny and Kelly can design a web site in 6 hours. Working alone however, Manny would design the web site in 2 hour less time than Kelly. How long would it take Kelly alone to design the web site?

Answer 1

Answer:

Step-by-step explanation:

total time taken by both of them = 6 hrs

let the time taken by kelly be x

then the time taken by manny would be x-2

6 hrs = x + x - 2

6 + 2 = 2x

8 hrs = 2x

8/2 = x

4 hrs = time taken by kelly alone
