Question

You start driving north for 4 miles, turn right, and drive east for another 4 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.

Answer 1

You end up 4 miles north and 4 miles east of the start, so the straight-line distance is √(4^2 + 4^2) = 4√2 ≈ 5.6569, which rounds to 5.7 miles.
