Stanley is a house painter. He receives a call from a potential customer who lives in a different city. The distance on a map between his business and the customer's house is 9 centimeters. The map uses a scale of 3 centimeters = 7 kilometers. What is the actual distance between Stanley's place of business and the customer's house?

1 answer

To find the actual distance, we need to convert the distance on the map to the actual distance using the scale given.

The scale is 3 centimeters = 7 kilometers.

Dividing both sides of the scale by 3, we get 1 centimeter = 7/3 kilometers.

Multiplying the distance on the map by this conversion factor, we have:

9 centimeters * (7/3 kilometers / 1 centimeter) = (9 * 7) / 3 kilometers = 63/3 kilometers = <<9*(7/3)=21>>21 kilometers.

Therefore, the actual distance between Stanley's business and the customer's house is 21 kilometers.
