Answer:

Answer:
6 seconds
Step-by-step explanation:
1/12 mile * 5280 feet/mile = 440 feet per train
50 miles/hour * 1/3600 hr/sec * 5280 ft/mile = 73 1/3 ft/second
one train has to travel 440 feet to pass the other train
440 feet * 1/(73 1/3) sec/ft = 6 seconds
The answer is 12.5 km/hr
45/3.6=12.5
They are similar, but I don't exactly know why. It has something to do with the angles, I know that.
