Final answer:
To find the distance from your house to your friend's house, you can use a map with a scale. Set up a proportion using the lengths on the map and the actual distance to find the answer.
Step-by-step explanation:
To find the distance from your house to your friend's house, you need to calculate the length of the path between the two points. This distance may not be the same as the straight line distance between the two points. If you have a map with a scale, you can use it to find the actual distance. For example, if the scale is 1.5 inches = 2 miles and the distance on the map is 4.5 inches, you can set up a proportion to find the actual distance.
First, let x be the actual distance in miles. The proportion would be:
1.5 inches / 2 miles = 4.5 inches / x miles
Cross multiplying, we get:
1.5 inches * x miles = 2 miles * 4.5 inches
Simplifying, we get:
x = (2 miles * 4.5 inches) / 1.5 inches
x = 6 miles
So the actual distance from John's house to Mike's house is 6 miles.
