Question

A map has a scale 1 inches : 10 miles. Use the given map distance to find the actual distance.

1. 3 in 2. 7.5 in 3. 1 ft

Answer 1

Answer:

1) $x = 30\,in$, 2) $x = 75\,mi$, 3) $x = 31\,mi$

Step-by-step explanation:

The actual distances are computed below:

1) The actual distance is:

$x = \frac{3\,in}{1\,in}\times 10\,mi$

$x = 30\,in$

2) The actual distance is:

$x = \frac{7.5\,in}{1\,in}\times 10\,mi$

$x = 75\,mi$

3) The actual distance is:

$x = \frac{3.1\,in}{1\,in}\times 10\,mi$

$x = 31\,mi$
