Answer:
Either 15 miles north 20 miles west or 20 miles north 15 miles west
The best route Filiz can take is the hypothenuse in which case he will drive only 25 miles
Step-by-step explanation:
The described route make us think of a right triangle.
Where the way north is one leg and the west way the other one
So we have two possibilities
1.- North way traveled is 15 miles and west way 20 miles
2.- North way traveled is 20 miles and west way 15 miles
Both cases end in a distance of 25 miles from the starting point according to Pithagoras Theorem
(25)² = (15)² + (20)² = 625
Taking √(25)² = 25 miles
The best route Filiz can take is the hypothenuse in which case he will drive only 25 miles
