Question

A map has a scale of 1 unit = 0.5 kilometer. Cities E and F are shown on the map.

According to the map, what is the actual straight-line distance between cities E and F, to the nearest tenth of a kilometer?

Answer 1

Explanation:

Horizontal distance (x) from E to F is 3 units = 1.5 km

Vertical distance E to F is 6 units = 3 km

Now use Pythagorean Theorem

d^2 = 1.5^2 + 3^2

d^2 = 11.25

d =3.4 km
