Question

You have travelled 25 kilometres.

Your friend's map gives the scale as:

20cm:100km.
How many cm on the map have you travelled?

Answer 1

5cm

Explanation:

okay what you need to know is that:

1cm:5km

5km times 5 is the distance you traveled, 25km

1cm times 5 is 5

Don't get confused with 5km to 5.

It's totally different.
