A runner is 22 km east and 15 km south of his starting point. How far is he in a direct line from his starting point?

Answer 1

√(22^2 + 15^2) = √709 = 26.627 km

Answer 2

Answer 3

Btw related to the question I asked: how long would it take him to return to his starting point in a direct line if he can run at 10 km per hour?

Answer 4

time = distance/speed, so 2.6627 hr
