To solve this question, find out the distance covered by both players and time taken by the winner to reach its goal. Since distance is given. Find out their speeds. covers in secs. Find out the distance covered out by in secs. The answer you will get, subtract it by as distance covered by that time. You will get the resultant answer.
Complete step-by-step answer:
Total distance given .
Time taken by secs.
Speed of Distance covered / Time taken

We should not consider the distance covered by one quantity in ‘km’ and the distance covered by another quantity in ‘m’.
Complete step-by-step answer:
Total distance given
Time taken by
Again, Distance covered by
Time taken by
Now, distance covered by
So, to get the distance by which A beats B, we will have to distinguish between the distance covered by A & B.
