Answer:
and
Step-by-step explanation:
Represent the swimmers with A and B
For Swimmer A:
For Swimmer B:
Required:
Write a parametric equation
For Swimmer A:
If swimmer A covers 54 meters in 1 minutes, then the swimmer covers 54t in t minutes
So, the function is:
For Swimmer B:
If swimmer A covers t minutes, swimmer B swims for (t - 3) minutes because swimmer B starts 3 minutes later.
<em>If in 1 minutes, swimmer B covers 134 minutes; In (t - 3) minutes, the swimmer covers 134(t - 3)</em>
<em></em>
So, the rate is:
Hence, the parametric functions are:
and
