If 4.5 inches on a map convers 270 miles, what is the scale of inches to miles?
45 inches/2700 miles = .01666.....inch/mile
or 5 inches/300 miles
or
1 inch / 6 miles :)
Damon -- I think you overlooked the decimal point. It's 4.5 inches = 270 miles.
That is why I wrote 45 not 4.5 and 2700
To find the scale of inches to miles, you need to calculate how many miles are represented by one inch on the map.
In this case, the given information states that 4.5 inches on the map represent 270 miles.
So, to find the scale, you divide the total number of miles by the total number of inches:
Scale = Total miles / Total inches
In this case, it would be:
Scale = 270 miles / 4.5 inches
Now, you simply perform the division:
Scale = 60 miles/inch
Therefore, the scale of inches to miles is 60 miles/inch. This means that every inch on the map represents 60 miles in real life.
4.5/270 = 1/x
Cross multiply and solve for x.
