Answer 2

Answer:

The average speed of the train is 62.525 km/hr.

Step-by-step explanation:

Given : A train travels a distance of 1000 km 400 m in 31:2 hours 30 minutes.

To find : What is the average speed of the train?    

Solution :

A train travels a distance of 1000 km 400 m.

Converting into km,

1 km = 1000 m

1 m = 0.001 km

400 m = $400\times \frac{1}{1000}=0.4$ km

Total distance covered is 1000+0.4=1000.4 km

Time taken by train is 31:2 hours 30 minutes.

i.e. $\frac{31}{2} hr +30 min$

$\frac{31}{2} hr +\frac{1}{2} hr$

$\frac{32}{2} hr=16 hours$

Total time taken by train is 16 hours.

The speed of the train is

$S=\frac{D}{T}$

$S=\frac{1000.4}{16}$

$S=62.525km/hr$

Therefore, The average speed of the train is 62.525 km/hr.
