Answer 1

Train 2 is traveling faster than train 1, because 50 km in 30 min = 5/3 km/min (≈1.6667 km/min) while 8 km in 5 min = 8/5 km/min = 1.6 km/min.

Train 2 is traveling faster than train 1, because in 60 minutes Train 2 goes 100 km but Train 1 goes only 96 km.

(Train 1 is not traveling faster than Train 2 because its speed, 1.6 km/min (96 km/h), is less than Train 2's 1.6667 km/min (100 km/h).)
