You and your friend hike to a waterfall that is 4 miles east of where you left your bikes. You then hike to a lookout point that is 2 miles north of your bikes. From the lookout point, you return to your bikes.
a. About how far do you hike? Assume you travel along straight paths.
I used Pythagorean theory to solve for the unknown distance from the waterfall to lookout point. a^2 + b^2 = c^2 2^2 + 4^2 = c^2 20 = c^2 Take square root of both sides 4.47 = c Rounded to 4.5 miles
Add 4 miles and 2 miles and 4.5 miles 10.5 miles total
