The Earth Revolves around the sun at 30,000 m/sec!!!Given that jogger runs 15km/hr As we know that 1 km/hr = 5/18 meter/sec ( 1 km=1000 meter, 1 hr=60×60 sec, Then 1 km/hr = 1000/3600 =5/18 ) So 15 km/hr =15×5/18 m/s Let jogger takes 'X' sec to complete 400 m Then X×(15×5/18)=400 X×(15×5)=400×1A train running at the speed of 60 km/hr crosses a pole in 9 seconds Find the length of the train
