Answer 1

Answer:

80

Explanation:

23:00 = 11hrs

16:00 = 4 hrs

total time taken for journey = 11-4= 7 hrs

Velocity= displacement/ time

= 560/7

= 80 kmph

Answer 2

Concept

Distance is the product of velocity and time.

Given

Chennai Egmore started at 16:00 and reaches Karaikudi at 23:00 and the distance covered is 560 km.

To Find

Velocity of the train.

Solution

Time taken to cover a distance of 560 km is 7 hours.

Substitute the known parameters in the formula $d=vt$ to determine the velocity of the train.

$d=vt\\v=\dfrac{560}{7}\\v=80 kmph$

Hence, the velocity of Chennai Egmore is 80kmph.
