A train covers a distance between two stations in 45 minutes. If its speed is reduced by 5 km/h, it covers the same distance in 48 minutes. Find the distance between the two stations.
A. 72 km
B. 60 km
C. 50 km
D. 80 km
Answer: Option B
Solution (By JKSSB Mock Tests)
Let initial speed be s. Distance is constant, so s * (45/60) = (s - 5) * (48/60) => 45s = 48s - 240 => 3s = 240 => s = 80 km/h. Distance = 80 * (45/60) = 60 km.
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.
