Question

A car travels 28 miles north and then turns east. How far did the car travel east if the destination is 53 miles from the starting point?

Answer 1

█ Explanation █

✦ Find the square of the hypotenuse. Let 'd' stand for the distance. 
✦ $53^{2} = 28^{2} + d^{2}$
✦ $53^{2} - 28^{2} = d^{2}$
✦ Solve for the difference.
✦ $(53+28)(53-28)= d^{2}$
✦ $81*25= d^{2}$
✦ $d^{2} = 2025$
✦ $d= \sqrt{2025} = 45 miles$

Answer: The car traveled 45 miles east.
