Answer:
500 ft
Step-by-step explanation:
What we know from the statement is that the scale of the map is 125 inches per inch.
Ie: 1 in / 125 ft
In theory then 1 foot on the map represents 125 feet on the actual.
You don't ask how many feet makes 5 fleas therefore:
1/125 = 4 / x
Solving for x we have:
x = 4 in * 125 ft / 1 in = 500 ft
Which means that 4 inches represents 500 feet in reality.
