Two trains each of 1160 meters are running in opposite directions with same speed. If they cross each other in 20 seconds, then what is the speed of each train in Km per second?

257.2 Km/hour

260 Km/hour

208.8 Km/hour

None of these

Total distance covered by both trains = 1160 + 1160 = 2320 meters

Time taken to cross each other = 20 seconds

Relative speed (combined speed of both trains) = Total distance / Time = 2320 / 20 = 116 meters/second

Since both trains have the same speed, the speed of each train = Relative speed / 2 = 116 / 2 = 58 meters/second

Convert meters/second to km/second: 58 / 1000 = 0.058 km/second (approximately)

Convert km/second to km/hour: 0.058 * 3600 = 208.8 km/hour
