Question

Answer 1

ANSWER

100 miles

EXPLANATION

The map legend says that 2 inches on the map equals 50 miles.

Towns A and B are 4 inches apart on the map.

Let the real distance be x.

We can compare these distances like this:

2 inches = 50 miles

4 inches = x miles

Cross-multiply:

2 * x = 4 * 50

Divide through by 2:

$\begin{gathered} x\text{ = }\frac{4\cdot\text{ 50}}{2} \\ x\text{ = 100 miles} \end{gathered}$

Towns A and B are 100 miles apart.
