Relative speed white running in opposite direction 12
Again, relative speed while running in same direction
As we know, velocity =
Lengths of the both trains = meter
Now, as the faster train exceeds the slower train in the same direction in seconds.
The length of the slower train = meter.
The length of the faster train = meter
(ans.) Faster train 168.75 meter & slower train 131.25 meter.

View AllIn 1 hour, one train goes (21-16)= 5 km more than another.
Now, In 1 hour total distance covered by them = (16+21) km = 37 km
If distance difference is 5 km then total distance = 37 km
If distance difference is 60 km then total distance = km
Distance between Dhaka and Chittagong is 444 km. (ans.)
First train speed v1= 72*5/18 =20 ms-1
Second train speed v2=54*5/18=15 ms-1
Required time=(100+120)/(20-15)=44 second
