Best Answer

Convert both measurements to the same units - choose the smaller unit, namely centimetres.

1000 metres = 1 kilometre

100 centimetres = 1 metre

28 km = 28 x 1000 x 100 = 2800000 cm

3.5 cm equates to 2800000 therefore 1 cm equates to 2800000/3.5 = 800000

The scale is 1 : 800,000

NOTE : A map scale often shows the relationship of a scale measurement on the map to the actual distance.

800000 cm = 800000/100000 = 8 kilometres.

1 centimetre represents 8 kilometres

1 equals 50miles if two towns are 5 apart on the map about how many miles apart are they?

Ok, so if 1 = 50 then you multiply 1 by 5 to get 5 because the towns are 5 apart, so then 50 multiplied by 5 is 250, so the two towns are 250 miles apart. Hope this helps!
