Question

2. A goods train starts running from a place at 1 P.M. at the
rate of 18 km/hour. Another goods train starts from the
same place at 3 P.M. in the same direction and overtakes
the first train at 9 P.M. The speed of the second train in
km / hr ​

Answer 1

Step-by-step explanation:

Distance cover by 1st train in 2hr = 18×2

Distance cover by 1st train in 2hr = 36km

time taken by second train to overtake 1st train= 9-3

both train is in same direction so relative speed = S-s

both train is in same direction so relative speed = S-18

time taken by second train to overtake 1st train= 6hr

a/q

distance = speed ×time

36= (S-18)×6

6= S-18

24=S

hence speed of second train is 24km/hr
