Two delivery cars start from the same warehouse at the same time in identical directions. The first tracks a constant speed of 45 km/h and the second runs at 55 km/h. What is the distance between them after 2 hours 30 minutes?
A. 30 km
B. 27 km
C. 25 km
D. 22 km
Answer: Option C
Solution (By JKSSB Mock Tests)
Relative speed = 55 - 45 = 10 km/h. Time = 2.5 hours. Distance separation = Relative Speed * Time = 10 * 2.5 = 25 km.
