A map has a scale of 1 cm : 11.5 km. Two cities are 5.5 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?

To find the actual distance between the two cities based on the map's scale, we can use the scale provided:

1 cm on the map corresponds to 11.5 km in reality.

Given that the two cities are 5.5 cm apart on the map, we can calculate the actual distance as follows:

\[ \text{Actual Distance} = \text{Map Distance} \times \text{Scale Factor} \]

Substituting the values we have:

\[ \text{Actual Distance} = 5.5 , \text{cm} \times 11.5 , \text{km/cm} \]

Calculating the product:

\[ \text{Actual Distance} = 5.5 \times 11.5 = 63.25 , \text{km} \]

Now, we need to round this to the nearest tenth of a kilometer:

\[ \text{Actual Distance} \approx 63.3 , \text{km} \]

Therefore, the actual distance corresponding to the 5.5 cm map distance is approximately 63.3 km.
