The equation: y = (1/1000) x
Step-by-step explanation:
if 3500meters = 3.5 km,
it means 1000 meters = 1 km
1 meters = 1/1000 km
if x = number of meters
y = number of kilometers
An equation for converting the number of meters to kilometers:
y = (1/1000) x
y = x/1000
Check: if x = 3500
y = 1/1000(3500) = 3.5km
