The scale for a map says that 1 cm is equal to 25 miles. Jennifer measures the distance between two cities as 4.5 cm. How far apart are the cities?
A) 90 miles apart
B) 112.5 miles apart
C) 128.5 miles apart
D) 149 miles apart
the correct answer is b mark because 1 = 25
so 4 cm =100 then you divide 25 in half since you have the .5 and you get 112.5
It is 112.5
To find the distance between the two cities, you can use the given scale of the map. The scale states that 1 centimeter on the map represents 25 miles in reality.
Since Jennifer measures the distance between the two cities as 4.5 centimeters, we need to find out how many miles 4.5 centimeters represents on the map. To do this, we can set up a proportion:
1 cm on the map is to 25 miles in reality as 4.5 cm on the map is to x miles in reality.
We can set up the equation as follows:
1 cm / 25 miles = 4.5 cm / x miles
Now, we can cross-multiply:
1 * x miles = 25 miles * 4.5 cm
x miles = 112.5 miles
Therefore, the two cities are 112.5 miles apart.
So, the correct answer is B) 112.5 miles apart.
