After a day hike, a group of hikers set up a camp 3 km east and 7 km north of the starting point. The elevation of the camp is 0.6 km higher than the starting point. What is the distance from the camp to the starting point?

This is the concept of trigonometry;
Using the Pythagorean theorem, the elevation of the starting point will be given by:
c^2=a^2+b^2
c^2=7^2-3^2
c^2=49-9
c^2=40
thus;
c=6.325 km
therefore the starting point of the camp was:
6.325-0.6
=5.725 km
The answer is 5.725
