A train 110 meters long is running at a speed of 58 km/h. How much time will it take to pass a man running at 4 km/h in the opposite direction?
Correct Answer: Option B
Explanation:
Relative speed = 58 + 4 = 62 km/h = 62 * (5/18) = 155/9 m/s. Time = Distance / Speed = 110 / (155/9) = 110 * 9 / 155 = 990 / 155 = 6.38 seconds.
Relative speed = 58 + 4 = 62 km/h = 62 * (5/18) = 155/9 m/s. Time = Distance / Speed = 110 / (155/9) = 110 * 9 / 155 = 990 / 155 = 6.38 seconds.

Excluding operational corridor stops, the speed of an inter-provincial bus is 60 km/h, and including stops it tracks at 48 km/h. How many minutes does it stop per hour?
Correct Answer: Option D
Explanation:
Stoppage time per hour = (60 - 48) / 60 = 12 / 60 = 1/5 hour. In minutes = (1/5) * 60 = 12 minutes.
Stoppage time per hour = (60 - 48) / 60 = 12 / 60 = 1/5 hour. In minutes = (1/5) * 60 = 12 minutes.

A car covers a distance of 100 km at 40 km/h and another 150 km at 50 km/h. Find the average speed for the complete trip.
Correct Answer: Option B
Explanation:
Total distance = 100 + 150 = 250 km. Time 1 = 100 / 40 = 2.5 hours. Time 2 = 150 / 50 = 3 hours. Total time = 5.5 hours. Average speed = 250 / 5.5 = 45.45 km/h.
Total distance = 100 + 150 = 250 km. Time 1 = 100 / 40 = 2.5 hours. Time 2 = 150 / 50 = 3 hours. Total time = 5.5 hours. Average speed = 250 / 5.5 = 45.45 km/h.
