It takes 36 minutes for 7 people to paint 4 walls How many minutes does it take 9 people to paint 7 walls?

To find the time it takes for 9 people to paint 7 walls, we first determine the rate at which the original group works. Seven people can paint 4 walls in 36 minutes, which means they can paint 1 wall in 36/4 = 9 minutes. Therefore, 9 people can paint 1 wall in 9/9 = 1 minute. To paint 7 walls, it would then take 7 minutes.

Each person has 3 people to call It takes 2 minutes to call 3 people. In 10 minutes how many people will have been called?

In 10 minutes, there are enough time slots to make 5 calls of 2 minutes each (10 minutes ÷ 2 minutes per call). Each person calls 3 people, so in each 2-minute call, a total of 3 people are contacted. Therefore, in 10 minutes, a total of 5 calls × 3 people per call = 15 people will have been called.
