Question

a railway train 200m long moves with a speed of 72km h calculate the time taken by the train to cross a bridge =0.8 long​

Answer 1

Answer:

Step-by-step explanation:

Total length to be crossed= Length of train +Length of bridge

                                            = 200 +800

                                            = 1000 m

Time Taken = Distance/speed

                    =  1000*3600/7200

                    = 50 Seconds
