Question

Two trains which are running in opposite direction meet each other after 2 mins, total distance travel by both trains is 1.8km. Find average of speed of both trains.​

Answer 1

Time taken =2min or 2/60 hours or 1/30 hrs

Distance = 1.8 km

Average speed of 2 trains = Total d/ Total t

=1.8*1/30

=1.8*30

=54 km/h

Average speed of one train =54/2 = 27km/h

Answer 2

Step-by-step explanation:

1 km=1000m

1.8 km=1800 m

1 min=60 s

2 min=120 s

Average speed=total distance/time taken

=1800 m/120 s

=15 m/s
