A car travels a distance of 300 km at a certain speed. If the speed is increased by 15 km/h, it takes 4 hours for the journey. Find the original speed.
A. 60 km/h
B. 55 km/h
C. 65 km/h
D. 70 km/h
Answer: Option A
Solution (By JKSSB Mock Tests)
New speed = 300 / 4 = 75 km/h. Since new speed is original speed + 15 km/h, the original speed = 75 - 15 = 60 km/h.
