Question

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?

Answer 1

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
