9.6

Step-by-step explanation:

THE CORRECT ANSWER IS 9.6!!

Answer 2

Given,

The length of the river = 480 km .

The map scale ratio = 1:5000000 .

To Find,

The length of the river on the map.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

We know that, If the map scale ratio is 1:5000000, therefore, this indicates that each 1 mm on the map is actually 5000000 mm in the real.

1km = 1×$10^{6}$ mm.

∴480km = 480×$10^{6}$ mm.

Suppose the length of the river 0n map is x mm.

So, we can say

$\frac{L_{map} }{L_{real}} = \frac{1}{5000000}$.

⇒$\frac{x}{480.10^{6} } =\frac{1}{5000000}$.

⇒$x=\frac{480}{5}$.

⇒x=96.

In that case, the length of the river on the map is 96 mm means 9.6cm.

Hence, The length of the river on the map is 9.6 cm.
