Two warships were moving toward each other in the same straight line at 50 km/h and 89 km/h respectively. One of the ships fired a shell toward the other when the distance to it was 4.2 km. Given that the shell's horizontal velocity relative to the first ship was 211 km/h, how long did it take for the shell to hit the second ship?
