Answers
Answer:
Speed of the train = 64.54 km/ hr.
and,
Average Speed of the train = 59.16 km/hr.
Step-by-step explanation:
As the question is stated,
The time at which the train left the station of Secunderabad = 7 P.M.
Time at which the train reaches Bhopal = 6 A.M.
Time for which the train stopped = 1 hour
Distance between the Secunderabad and Bhopal = 710 km
Now,
Total time taken by the train = 11 hours of travelling time + 1 hour of rest time
So,
Speed of the train is given by,
\begin{gathered}Speed=\frac{Distance}{Time}\\Speed=\frac{710}{11}\\Speed = 64.54\, km/hr.\end{gathered}
Speed=
Time
Distance
Speed=

710
Speed=64.54km/hr.
Because, the Speed is the ratio of the distance and the travelling time of the train.
Therefore, Speed of the train is 64.54 km/ hr.
Now,
Average Speed of the train is given by,
\begin{gathered}Average\ Speed =\frac{Total\ Distance}{Total\ time}\\Average\ Speed = \frac{710}{12}\\Average\ Speed = 59.16\ km/hr.\end{gathered}
Average Speed=
Total time
Total Distance
Average Speed=

710
Average Speed=59.16 km/hr.
As, the Average speed of the train also includes the time for which the train rested.
Therefore, the Average Speed of the train is 59.16 km/hr.

Speed = 64.54 km/ hr
Because, the Speed is the ratio of the distance and the travelling time of the train.
Therefore, Speed of the train is 64.54 km/ hr.
Now,
Average Speed of the train is given by,
Average Speed = Total Distance
Total Time
Average Speed = 71O

Average Speed = 56.16 km/ hr
As, the Average speed of the train also includes the time for which the train rested.
Therefore, the Average Speed of the train is 59.16 km/hr.
