Answer:
the correct answer is option c that is 187.5m.
explanation :
Given is
T1= 15 ms
T2 = =20 ms
we have to find out distance=?
We know that
distance of first train = (15) ^ 2)/2 = 112.5m
Similarly,
another train travels distance =
(20) ^ 2/(2) = 200m
Depration
= 500-(112.5+200)
= 500-302.5
=187.5 m
the correct answer is option (c) that is 187.5m
