IF U WANT TO MARK UR ANS. BRAINLIEST BY ME THEN ATLEAST 2 PEOPLE SHOULD ANSWER MY QUESTION.

Sensible answer to be marked as the brainliest.

Answer 1

speed= 50km/hr
50000m
=3600sec.
total distance =210+165=375m
it covers 50000m distance in 3600sec
,so In Y sec it covers 375 m
50000/3600=375/Y
Y= 3600*375/50000
=27sec.
there fore, the train covers 375m in 27 sec.
hope this helps to you
