A high-speed train clears a stationary post column signal mast in 8 seconds and clears across the full station platform itself, which measures 240 meters long, in 20 seconds. Find the speed index of the train in km/h.
Correct Answer: Option C
Explanation:
Time taken to cross the platform span alone = 20 - 8 = 12 seconds. Speed of train = 240 / 12 = 20 m/s. In km/h index = 20 * (18/5) = 72 km/h.
Time taken to cross the platform span alone = 20 - 8 = 12 seconds. Speed of train = 240 / 12 = 20 m/s. In km/h index = 20 * (18/5) = 72 km/h.

A modern coach bus covers a distance of 280 km in 4 hours 40 minutes. Find its average speed.
Correct Answer: Option B
Explanation:
Time = 4 hours 40 minutes = 4 + 40/60 = 4.666 hours = 14/3 hours. Speed = Distance / Time = 280 / (14/3) = 280 * 3 / 14 = 20 * 3 = 60 km/h.
Time = 4 hours 40 minutes = 4 + 40/60 = 4.666 hours = 14/3 hours. Speed = Distance / Time = 280 / (14/3) = 280 * 3 / 14 = 20 * 3 = 60 km/h.

Excluding institutional stops, a transit bus routes at 60 km/h and including stops it runs at 50 km/h. How many minutes does the bus stop per hour?
Correct Answer: Option C
Explanation:
Stoppage time per hour = (60 - 50) / 60 = 10 / 60 = 1/6 hour = 10 minutes.
Stoppage time per hour = (60 - 50) / 60 = 10 / 60 = 1/6 hour = 10 minutes.
