A train without stopping travels 60 km/h and with stoppage 40 km/h. What is the time taken for stoppage on a route 300 km?
A. 10 hours
B. 20 hours
C. 5 hours
D. 2.5 hours
Answer: Option D
Solution(By Examveda Team)
Since, the train travels at 60 km/h, it's speed per minute is 1 km per minute. Hence, if it's speed with stoppage is 40 km/h, it will travel 40 minutes per hour i.e. train stops 20 min per hour. Time taken to travel 300 km with stoppage, $$ = \frac{{300}}{{40}} = 7.5\,\,{\text{hours}}$$ Time taken for stoppage as it stops for 20 min per hour= 7 × 20 + 10
= 140 + 10
= 150 minutes.
= $$\frac{{150}}{{60}}$$ hours = 2.5 hours.

at 60 km/hr
t=300/60=5 hrs
at 40 km/hr
t=300/40=7.5
so time df=7.5-5=2.5 hrs..(ans)
