2 answers

4cm is 4 times as big as 1 cm, so
you want a distance 4 times as big as 4km.
First change 4 km to cm.
If 0.00001km = 1cm
4km = x
x = 4km divided by
0.00001 which will give you 400000.
So 400000 multiplied by four which is 1600000, is your answer in cm. So change it back to km using the dimensions given.
