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=

11

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=

12

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.

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

Speed = Distance

                  time

Speed = 71O

                11

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

                               12

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.
