if 1/4 inch equals 40 mi, how many miles is a 1/2 inch?
Set up ratios:
(1/4) / 40 = (1/2) / x
Solve for x.
75 miles
75 miles 150
80
To find out how many miles are in 1/2 inch, we need to use the given conversion factor of 1/4 inch equals 40 miles.
Since we know that 1/4 inch is equal to 40 miles, we can set up a proportion to find the number of miles in 1/2 inch.
Let's set up the proportion:
1/4 inch = 40 miles
1/2 inch = x
To solve this proportion, we can use cross multiplication. Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and vice versa.
(1/4) * x = (1/2) * 40
Now, let's simplify both sides:
x/4 = 40/2
x/4 = 20
To isolate x, we can multiply both sides of the equation by 4:
x = 20 * 4
x = 80
Therefore, 1/2 inch is equal to 80 miles.
