distance covered in
40 seconds=850 m
1 hour=60×60=3600 secs
distance covered=850×3600/40
=7600 m
40 seconds=850 m
1 hour=60×60=3600 secs
distance covered=850×3600/40
=7600 m

Distance covered on 40sec=850m
Distance covered on 1sec=850m/40=21.25. |By unitary method
Distance covered on 60sec=60×21.25=1275m
So, the ans is 1275m
Distance covered on 1sec=850m/40=21.25. |By unitary method
Distance covered on 60sec=60×21.25=1275m
So, the ans is 1275m
Sorry, it was mistyped, enter typed suddenly:-) :-P
After that multiply 1275 by 60 to get 76500 as the sender exact ans of 76500.
