Question

"a man drove 11 mi directly east from his home, made a left turn at an intersection, and then traveled 2 mi north to his place of work. if a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?"

Answer 1

pythagorean therom!


east and the north make a right angle

a^2 + b^2 = c^2
(11)^2 + (2)^2 = c^2
121 + 4 = c^2
125 = c^2
11.2 miles = c
