Question

A train 210 m long took 12 seconds to pass a 90 m long tunnel. Find the speed of the train.
​

Answer 1

net distance covered =300m

total time taken 12sec

velocity =300/12=25

Answer 2

Answer:

10 m/s

Step-by-step explanation:

the length of the train= 210m

length of the tunnel= 90m

distance covered by the train= 210-90

                                                = 120m

time taken =12 secs

speed=distance/time

         =120/12

Speed of the train is 10 m/s.
