ANSWER

C. 108 miles

Think of this problem as figuring out the hypotenuse of a triangle. After 3 hours, bus A will have traveled 60 miles (leg A). Bus B will have traveled 90 miles (leg B). To figure out the hypotenuse, simply use a² + b² = c²

(60²)+(90²)=c²
3600+8100 = c²
11700 = c²
c = ~108 miles
