Marks: +1, -0

In a two kilometer race, A beats B by 54 metres or 8 seconds. Find A’s time over the course.

288.3 seconds
261.6 seconds
250.17 seconds
3,471.6 seconds
None of these

Solution:

{\winner's \time}/{\loser's \time}

=

{\winning \time + \start \time}/{\winning \distance + \start \distance}

{\A's \time}/{2000-54}

=

{8+0}/{54+0}

{\A's \time}/{1946}

=

8/{54}

⇒ A’s time =

{8×1946}/{54}

= 288.3 seconds
