On a map, 1.5 cm represents 210 km. What actual distance corresponds to a map distance of 30 cm?

Let the actual distance be x so:

[tex] \frac{1.5cm}{210km} = \frac{30cm}{xkm} \\ (1.5cm)(xkm)=(210km)(30cm) \\ 1.5x=6300 \\ x=4200[/tex]

Therefore the actual distance is 4200km

The ratio is:
1.5 cm:210 km

Convert:
[tex]30 cm(\frac{210 km}{1.5 cm})[/tex]
=4200 km

Hope this helps =)
