To find the speed of each train, we can use the formula:

Speed = Distance / Time

Given that the length of each train is 120 meters and they cross each other in 12 seconds, we can calculate the total distance covered by both trains as the sum of their lengths:

Total distance = 120 meters + 120 meters = 240 meters

Now, we need to convert the time from seconds to hours, as the speed is usually measured in kilometers per hour. There are 3600 seconds in an hour, so:

Time = 12 seconds / 3600 = 0.00333 hours

Finally, we can substitute the values into the formula to find the speed:

Speed = 240 meters / 0.00333 hours

Calculating this, we get:

Speed = 72000 meters per hour

To convert this to kilometers per hour, we divide by 1000:

Speed = 72 kilometers per hour

Therefore, the speed of each train is 72 kilometers per hour.
