Question

If you travel south from the equator to 25°S, how far will you have to travel? The circumference of the earth is approximately 40,000 km or 24, 900 mi.

Answer 1

2,777.8 km or 1,729.2 mi

Explanation:

first think about how many degrees would you travel if you wanted to do a whole circunference always going south: it would take 360 degress to complete a circunference.

Then you can use a rule of three to find the answer:

If the whole circunference is 40,000km and in degrees is 360, then how much 25 degrees would be?

`x= (25)/(360)*40,000`

`x= 2777.8`
