Dalton made a scale drawing of a swimming pool. The scale he used was 1 millimeter : 5 meters. The actual width of the pool is 25 meters. How wide is the pool in the drawing?

millimeters

To find the width of the pool in the drawing, we need to convert the actual width of the pool to the scale of the drawing.

The scale ratio is 1 millimeter : 5 meters.
So, for every 5 meters in reality, there is 1 millimeter in the drawing.

To find the width in the drawing, we divide the actual width of the pool by the ratio:
Width in the drawing = Actual width of the pool / Scale ratio

Width in the drawing = 25 meters / 5 meters = 5 millimeters

Therefore, the width of the pool in the drawing is 5 millimeters.
