Question

How do you find the distance between San Jose and Brisbane on a map with a scale of 1 in : 8 mi if they are actually 48 mi apart.

Answer 1

Scale used in map is 1 inch = 8 miles.
actual distance = 48 miles.
if 8 miles is represented in 1 inch,
1 mile will be represented in = $\frac{1}{8}\ inch$
48 miles will be represented in = $48 \times \frac{1}{8}=\boxed{6\ inch}$
