distance between 2 cities scale is 1/2=20 miles. 55 miles apart
Pray and ask God to help you
.5 whatever = 20 miles
55 miles * .5 whatevers / 20 miles = 55/40 = 1.375 whatevers
To calculate the actual distance between the two cities, which are 55 miles apart on a scale of 1/2 = 20 miles, you can use the proportion method.
Let's assume the actual distance between the two cities is represented by "x" miles.
Using the proportion, we can set up the equation:
(1/2) / 20 = x / 55
To solve for x, we can cross-multiply and then solve for x:
(1/2) * 55 = 20 * x
55/2 = 20x
Divide both sides by 20:
x = (55/2) / 20
Simplifying the right side:
x = 55/40
Reducing the fraction:
x = 11/8
Therefore, the actual distance between the two cities is 11/8 miles.
To calculate the actual distance between two cities based on a given scale, you can use the following formula:
Actual Distance = Map Distance / Scale
In this case, the scale is given as 1/2=20 miles, which means that 1 unit on the map represents 20 miles in reality.
Let's calculate the actual distance between the two cities, given that they are 55 miles apart on the map:
Actual Distance = 55 miles / 20 miles
Actual Distance = 2.75 units
Therefore, the actual distance between the two cities is 2.75 units, based on the given scale.
