A motor vehicle completes a journey in 5 hours. It handles the first half of the stretch at 50 km/h and the second half at 30 km/h. Find the total distance wrapped.
A. 175 km
B. 200 km
C. 192 km
D. 187.5 km
Answer: Option D
Solution (By JKSSB Mock Tests)
Let the half distance be d. d / 50 + d / 30 = 5 => 8d / 150 = 5 => 8d = 750 => d = 93.75 km. Total distance = 2d = 187.5 km.
