If 3/ 8 in. on the map represents 25 mi, find the number of miles between the two cities
To find the number of miles between the two cities, we need to convert the fraction on the map to miles.
Given that 3/8 inch on the map represents 45 miles, we can set up a proportion to solve for the total number of miles between the two cities.
Let "x" represent the number of miles between the two cities.
We can set up the proportion as follows:
(3/8 inch) / (x miles) = (45 miles) / (1 inch)
To solve for "x," we can cross-multiply and solve for "x":
(3/8) * (1 inch) = (x miles) * (45 miles)
(3/8) * (x miles) = (1 inch) * (45 miles)
Now, let's solve for "x":
(3/8) * (x miles) = 45 miles
To isolate "x," we can multiply both sides of the equation by 8/3:
(8/3) * (3/8) * (x miles) = (8/3) * (45 miles)
(x miles) = 120 miles
Therefore, the number of miles between the two cities is 120 miles.
