Question 1207186
The bearing from City A to City B is Upper N 41 degrees Upper E. The bearing from City B to City C is Upper S 49 degrees Upper E. An automobile driven at 65 mph takes 1.4 hours to drive from City A to City B and takes 1.6 hours to drive from City B to City C. Find the distance from City A to City C.​ (Neglect the curvature of the​ earth.)

From A to B 
Distance 

65*1.4 = 91 miles

From B to C 
65*1.6 = 104 miles

Now the angle ABC (49+41)=90 deg by geometry (parallel lines and transversal)

AC^2 = AB^2 +BC^2

AC^2 = 91^2+104^2

AC = sqrt(91^2+104^2)
