Daisy is given a scale drawing with the route to her campsite.
The route to the campsite is 28 cm on the drawing.
The scale on the drawing is 1:300
What is the actual length of the route?
metres
Given that :
The route to the campsite is 28 cm on the drawing.
The scale on the drawing is 1:300
To find,
The actual length of the route.
Solution,
Let the actual length of the route be x.
Here, map distance : actual distance = 1: 300
[tex]\dfrac{1}{300}=\dfrac{28}{x}\\\\x=28\times 300\\\\x=8400\ cm[/tex]
