On a map, 3 inches represent an actual distance of 42 miles. if the actual distance between two cities is 322 miles, how many inches apart will the two cities be on the map ?

Two cities are 23 inches apart on the map

Step-by-step explanation:

on a map, 3 inches represent an actual distance of 42 miles.

the actual distance between two cities is 322 miles

Let x be the inches apart on the map

Lets make a proportion

Cross multiply and solve for x

Divide both sides by 42

x= 23

Two cities are 23 inches apart on the map

a² + b²= c²

24² + 7² = c²

c= 25

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
