Question :-

While crossing a tunnel 150 m long; a train of length 200 m, how much distance  travelled by train?

Answer :-

➡ Take the speed of of the second train = x km / hr.

➡ Cover a distance = sum of length of the trains

150+ 100 = 250 m.

➡ Change into kilometer

= 250/1000 = 0.25

➡Obtain their relative speed ( x + 30 ) km / hr

➡Find out of the out taken

( 10 sec = 10/ 3600 hr)

➡ Equate it's to 10 sec and solve for

( x + 30 ) = ( 0.25 / 10 ) ✖ 3600

➡ x = 60 km / hr
