Question

I am sitting in a train that is moving at a speed of 60 kilometers per hour
(kmph). If a train now passes in the opposite direction at a speed of 80 kmph,
what would its speed APPEAR to be to me?
A. 20 kmph in the direction of B. 20 kmph in the direction opposite to
my train
my train
C. 140 kmph in the direction of D. 140 kmph in the direction opposite
my train
to my train.​

Answer 1

Answer:

140 kmph....coz we add velocities when trains are running in opposite directions

Answer 2

Answer:

B

Because due to relative velocity the value becomes -20 i.e. 20 kmph in opposite direction.

Hope this answer helps you ^_^ !
