Answer:
after 2.5 hour passenger train would overtake .
Step-by-step explanation:
A freight train leaves a station at noon traveling at 30 mph.
A passenger train leaves 1 hour later travelling at 50 mph
Let the time to leave the station of freight train = t
time to leave passenger train = t - 1
Since distance = speed × time
the expression will be :
30t = 50(t - 1)
30t = 50t - 50
30t - 50t = -50
-20t = -50
t = [tex]\frac{-50}{-20}[/tex]
t = 2.5 hours
After 2.5 hours passenger train would overtake the freight train.
