If 3/4 of an inch on a map is equal to 45 miles, what does 1 inch represent?

(45 miles / 0.75 in) * 1 in = (45/0.75) miles = 60 miles

3/4=45

1=x

3x/4=45

3x=180

To find out what 1 inch represents on the map, we can use a proportion:

Let x represent the number of miles that 1 inch represents.

We are given that 3/4 of an inch is equal to 45 miles. Thus, we can set up the following proportion:

3/4 inch = 45 miles
1 inch = x miles

By cross-multiplying, we can solve for x:

(3/4) * x = 1 * 45

Multiplying both sides:

3x / 4 = 45

Next, we will multiply both sides by the reciprocal of 3/4, which is 4/3:

(4/3) * (3x / 4) = (4/3) * 45

The 3 on the left side cancels out with 3 in the denominator on the right side:

4x = 60

Finally, divide both sides by 4 to solve for x:

x = 60 / 4

Simplifying the division:

x = 15

Therefore, 1 inch on the map represents 15 miles.

To find out what 1 inch represents on the map, we can use a proportion.

Let's set up the proportion:
(3/4 inch) / (45 miles) = (1 inch) / (x miles)

To solve for x, we can cross-multiply:
(3/4 inch) * (x miles) = (1 inch) * (45 miles)

Next, we can simplify the expressions:
(3/4) * x = 45

To isolate x, we can multiply both sides by the reciprocal of (3/4), which is (4/3):
x = (45) * (4/3)

Finally, we can calculate the value of x:
x = 60

Therefore, 1 inch on the map represents 60 miles in reality.
