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?
A. 12 minutes
B. 10 minutes
C. 15 minutes
D. 14 minutes
Answer: Option A
Solution (By JKExamLibrary)
Stoppage time per hour = (60 - 48) / 60 = 12 / 60 = 1/5 hour. In minutes = (1/5) * 60 = 12 minutes.
Two trains start from stations A and B and travel towards each other at speeds of 50 km/h and 60 km/h respectively. At the time of their meeting, the second train has traveled 120 km more than the first. Find the distance between A and B.
Explanation:
Let the time they travel before meeting be t hours. Distance difference = 60t - 50t = 10t = 120 km => t = 12 hours. Total distance = (50 + 60) * t = 110 * 12 = 1320 km.
Explanation:
Speed of B = 400 / 50 = 8 m/s. Distance covered by B when A crosses the finish line at 45 seconds = 8 * 45 = 360 meters. Winning margin = 400 - 360 = 40 meters.
