A truck travels 20 miles due north, 30 miles due east, and then 20 miles due north. How many miles is the truck from the starting point?
Choose the correct choice:
A) 20.3  B) 44.7  C) 50  D) 70  E) 120
We have two right angle triangles with sides 20 and 15   The distance between starting and end point = sum of the hypotenuse of both the triangles.   Hypotenuse = [400 + 225]^(1/2) = 25   Hence the total distance between end point and starting point = 25 + 25=
