1. When we got to my aunt’s house, we asked her the location of the best places in the city and she provided us with a sketch which 4 centimeters of the sketch represented 500 meters of reality, we decided to go to a river that is 6 centimeters from the house in the sketch, how far will this river really be from the house?

• Answer: since 4 centimeters represent 500 meters, 1 centimeter will represent.
• 500: 4 = 125 meters. Since 1 centimeter represents 125 meters, 6 centimeters will represent. 125x 6 = 750 meters. The river is at a distance of 750 meters from the house.
