Train p takes 60 seconds to cross a pole by traveling at 18 km/h speed. Train q, which is 50% longer than train p takes 30 seconds to cross a pole. Find the time (in seconds) taken by train q to overtake train p. Select one:
a. 105
b. 125
c. 90
d. 75

length of train p =5×60(18km/h=5m/s)=300
length of train q=50%of length p+length of p
=450m
speed of train q =450/30=9m/s
so here real question begin
9t-5t= some distance between them initially I think you forgot to mention distance initially
