Answer 2

GiveN:-

Rajdhani express leaves Delhi station 9am and reaches Agra station at 11:30. If the distance between Agra and Delhi is 240km.

To FinD:-

The speed of the train.

SolutioN:-

We know that,

$\large{\green{\underline{\boxed{\bf{Speed=\dfrac{Distance}{Time}}}}}}$

• Distance between Agra and Delhi is 240km.
• Time taken to reach Agra from Delhi is 9 am to 11:30 am = 2½ hours = 5/2 hours

Putting the values,

$\large\implies{\sf{Speed=\dfrac{Distance}{Time}}}$

$\large\implies{\sf{Speed=\dfrac{240}{\frac{5}{2}}}}$

$\large\implies{\sf{Speed=240\times\dfrac{2}{5}}}$

$\large\implies{\sf{Speed=\cancel{240}\times\dfrac{2}{\cancel{5}}}}$

$\large\implies{\sf{Speed=48\times2}}$

$\large\therefore\boxed{\bf{Speed=96\:km/hr.}}$

The speed of the train is 96 km/hr.
