Remember the product of the means is equal to the product of the extremes.

anonymous · Answer

take a refractive scale here it is 2cm/5km=1/25000
ie 1 cm on map is 25000 cm in real world taking that into consideration
15.75km is 157500x 1/25000=answer

radar · Answer

5km x = 2 cm * 15.75 km
x=(2 * 15.75)/5
x= 6.3 cm
This is using proportion as required by the problem.
