All the runners have the same starting point and each runner maintains a uniform speed throughout the race. If the fastest runner runs at twice the speed of the slowest runner, what is the time taken by the fastest runner to finish the race? $20$ min $15$ min $10$ min $5$ min Quantitative Aptitude cat2003-1 quantitative-aptitude speed-distance-time + – go_editor asked Feb 7, 2016 edited Apr 2, 2022 by Lakshman Bhaiya go_editor 13.8k points 1.3k views answer comment Share See all 0 reply Please log in or register to add a comment.
