Question

The length of one train is 200 meters. The 300-meter-long train crossed a pole in 40 seconds. What is the speed of the train per hour?​

Answer 1

Speed =Distance÷Time ,

So,200m and 300m are distance add them

Its 500m now.

Then divide 500 by 40

=500÷40=12.5m/sec

So, 12.5×18÷5=45km/hr

We multiplied 12.5 with 18 by 5 because we have to convert it into km/h
