What constant speed must the second swimmer have in order to catch up to the leader at the end of the pool?

One swimmer in a relay race has a 0.465 s lead and is swimming at a constant speed of 4.86 m/s. He has 47.4 m to swim before reaching the end of the pool. A second swimmer moves in the same direction as the leader. What constant speed must the second swimmer have in order to catch up to the leader at the end of the pool?|||So figure out how much time it will take for the leader to finish. 47.4 / 4.86...





Then figure out how many meters behind the second swimmer is. 4.86 m/s x 0.465 s = lead distance





The second swimmmer must cover 47.4 + the lead distance in the same time as the leader.|||Who cares. Do your own homework.
