Here is the problem:

If Bill takes 3 hours to paint a room and James takes 5 hours to paint a room, how long will it take to paint a room if they work together? Show your working.

Thank You.

This question should be migrated, and the answers will follow.

Consider Bills rate is 1/3 rooms per hour. James is 1/5 rooms per hour. Together, 8/15 rooms per hour. so 15/8 hours for one room.
