Question

You determine that 2.3 cm on the map represents 300 km. You choose to include a bar representing a distance of 500 km.

How many centimeters should the bar extend?

Answer 1

3.83cm

Step-by-step explanation:

first, convert the 300km you're given to cm, giving you 30,000,000 cm. Then take this number and divide the 2.3cm by it. You should get .000000077cm. Next, use this number as your ratio to find what 500km would be represented by in cmxkm on this map. Finally, using the unit conversion of 1km=100,000cm, convert our last answer to cm by canceling out your km unit, giving you your final answer of 3.83cm.
