Geometry Question

Question

You start driving south for 2 miles, turn left, and drive east for another 9 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

south for 2 miles, then left for 9 miles means then east for 9 miles

construct a right triangle, with legs 2 and 9

then hypotenuse squared = 2^2 + 9^2

d= sqr(4+81) = sqr85

distance = about 9.22 miles as the crow flies from start to finish

rounded to the nearest 1/10 = 9.2 miles = 9 1/5 miles
