+204 An express train travels 90 kilometers per hour from Smallville to Megatown. A local train takes 2.5 hours longer to travel the same distance at 50 kilometers per hour. How far apart are Smallville and Megatown.
+37146 Let 'x' equal time for mega train
Slower train time is x + 2.5
90 km/hr * x hr = Distance = (x+2.5)hr * 50 km/hr
90x =(x+2.5)50
90x = 50x + 125
40x = 125
x = 125/40 = 3 5/40 hr = 3 hours 7.5 min
3 5/40 hr * (90km/hr) = 281.25 km apart
