1. Distance covered =120m+160m=280m

   Time taken =14 seconds

   Speed =Distance / Time

   =20m/s

   In second case,distance

   =120m+100=220m

   Time taken +220/20

   So , after reducing 220/20 answer will come 11seconds ..

   Total answer is 11 seconds

   I hope it would help u to solve this sum and u understood this sum !!
