Zinaida [17]

Answer:

The actual distance between the two places to the nearest tenth of a kilometer is 63.3 km

Step-by-step explanation:

Here, we want to get the actual distance between two places on a map, given the scale used to draw the map and the distance of both places on the map, in terms of the scale.

The scale used here is 1cm to 11.5km

Since 1cm = 11.5km

then 5.5cm = x km

Thus ; x = 5.5 * 11.5

x = 63.25 km

Our answer in wanted to the nearest tenth of a kilometer so the answer is 63.3 km
