Two Vande Bharat Trains of lengths 322 m and 623 m are running in opposite directions on parallel tracks at the speed of 190 km/h and 188 km/h.  In what time (in seconds) will they cross each other?

9

Total length  =  322 + 623 = 945 meters

Total speed  =  190 + 188 = 378 km/h

Time taken to cross each other =  \(\frac{945}{378 × 5/18}\) = 9 seconds
