Question

a train crosses a bridge of the length 1km in 2 minutes if the length of the train is half of the bridge, then the speed of the train iş-​

Answer 1

Answer:

we have length of the bridge= 1000m(1km)

train length is half of the bridge length =500 m

now combine the above two = 1500m

time =120 seconds (2minutes)

speed of the train =1500m÷120s

=12.5 m/s (45kmph)
