Excluding stoppages, the speed of a regional transit bus is 48 km/h and including stoppages it is 40 km/h. For how many minutes does the bus stop per hour?
A. 12 minutes
B. 8 minutes
C. 10 minutes
D. 15 minutes
Answer: Option C
Solution (By JKExamLibrary)
Stoppage time per hour = (48 - 40) / 48 = 8 / 48 = 1/6 hour. In minutes = (1/6) * 60 = 10 minutes.
A passenger train 100 meters long clears a line worker tracking on the ballast track in 5 seconds flat when both move along the identical direction. If the line worker walks at 8 km/h, find the train speed.
