A delivery van driver walks at 5 km/h and arrives 12 minutes late at his drop station. If he tracks at 8 km/h, he reaches 3 minutes early. Find the sector distance.
A. 4.00 km
B. 3.0 km
C. 3.33 km
D. 3.66 km
Answer: Option C
Solution (By JKSSB Mock Tests)
Time difference = 12 - (-3) = 15 minutes = 1/4 hours. Let distance be d. d/5 - d/8 = 1/4 => 3d/40 = 1/4 => 3d = 10 => d = 3.33 km.
