How many millimeters on the map would represent 700 meters in reality if the map has a 1 to 10,000 scale?

First we need to make sure we're working in the same units, so let's convert our 700 meters to millimeters. We multiply by 1000, so that's 700,000 millimeters

Map scales are a ratio. 1 to 10,000 is the same as the map measurement to 700,000

So if we rearrange and simplify, 700 meters in reality is 700,000 over 10,000, or 70 milliimeters on the map.
