Two trains of length 270 m and 300 m travelling a

Question

Two trains of length 270 m and 300 m travelling at 54 km/h and 36 km/h respectively, enter a two-track tunnel 430 m long simultaneously on different tracks and from opposite directions. After they cross each other, in how much time will the tunnel be free of the trains?

ABHIJEET SHUKLA · Accepted Answer

After 16 seconds, trains meet. After 20 more seconds, trains cross fully. Train 1 requires 70 seconds to cross the tunnel completely. Hence, it'll take 70-(16+20)=34 seconds for the tunnel to be completely free, once trains have crossed each other.............................................
