Scale of 1cm to 10km

is the same as saying 10mm to 10km

if you know that 10mm represents 10km you can work out what 50mm represents.

Hope that helps :)

How would you express 54mm as centimetres?

If 1cm is 10km, what would 5cm be?

If 1cm is 10km, what would 1mm be? (1mm is one-tenth of 1cm.) What would 4mm be?

1cm = 10mm, so 54mm = 5.4 cm

If 1cm= 50 km so 5.4 cm =54 km

am I right?

To work out what 54mm is, you need to know what 1mm is.
If 1cm represents 10km
Then:.10mm represents 10km
And:. 1mm represents 1km
So :. 54mm represents 54 x 1km
". ". 54 km
