Excluding the stoppage of the metro station, the speed of the metro train is 60 kilometers per hour and including the station stop, it is 48 kilometers per hour. How many minutes does the metro train stop every hour? A. 9 minutes B. 8 minutes C. 12 minutes D. 14 minutes Correct Answer C

Given:

Speed of the metro train excluding stoppages = 60 km/hour

Speed of the metro train including stoppages = 48 km/hour

Formula used:

Speed = Distance/Time

Calculation:

According to question

Loss in speed when including stoppages = 60 − 48 = 12 km/hour

⇒ In 1-hour train covers 12 km less due to stoppages

Hence, the time in which the Train stops per hour

⇒ Time is taken to cover 12 km

Speed = Distance/Time

⇒ 60 = 12/Time

⇒ Time = 12/60 = 1/5 hour

⇒ Time = 1/5 × 60 = 12 minutes

∴ The metro train stops 12 minutes every hour

There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
