On a map of the Fox River, 1 centimeter represents 2.5 kilometers. If a trail by the river is actually

9.50 kilometers long, what is the length of the river on the map?
A) 3.8 centimeters B) 2 centimeters C) 5.8 centimeters D) 7 centimeters
i don't know the formula

9.5 / 2.5 = ?

What about the 1 centimeter?

What about it?

The quotient of the problem is the length of the river on the map.

To solve this problem, you can use the concept of scale on the map. The scale tells you how much distance on the map represents a certain distance in reality. In this case, the scale is given as 1 centimeter represents 2.5 kilometers.

To find the length of the river on the map, you need to figure out how many centimeters would represent 9.50 kilometers. You can set up a proportion to solve for this.

Let "x" represent the length of the river on the map (in centimeters). The proportion can be written as:

1 cm / 2.5 km = x cm / 9.50 km

To solve for x, you can cross-multiply and then divide:
x cm = (1 cm / 2.5 km) * 9.50 km
x cm = 3.8 cm

Therefore, the length of the river on the map is 3.8 centimeters.

So the answer is:

A) 3.8 centimeters
