Given,
The distance travelled by train, d=2650 km=2650×10³ m
The time interval in which the train covers the total distance, t=9.00-2.00=7.00 hrs
That is, t=7×3600 s=25200 s
The average speed is given by the ratio of total distance travelled to the total time duration.
That is,
[tex]s=\frac{d}{t}[/tex]On substituting the known values,
[tex]\begin{gathered} s=\frac{2650\times10^3}{25200} \\ =105.16\text{ m/s} \end{gathered}[/tex]Thus the average speed of the train is 105.16 m/s
