Hi, i need help with the following:(adsbygoogle = window.adsbygoogle || []).push({});

One swimmer in a relay race has a 0.50-s lead and is swimming at a constant speed of 4.0 m/s. He has 50 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?

I understand that since the 1st swimmer swims at constant speed, he has zero accelaration.

Is it useful to use this formula? Speed = Distance / Time

If not, which formula can i use?

Thanks.
