Answer:
C: 590 meters
Explanation:
Let's start by finding Raymond's rate of swimming for meters per minute. We know that he can swim 236 meters in 6 minutes. So let's divide 236 by 6 to find how far Raymond can swim in 1 minute.
236 / 6 = 39.3
So if we know Raymond can swim 39.3 meters in 1 minute, we multiply 39.3 meters by 15, to find how far he can swim in 15 minutes.
39.3 * 15 = 589.995 which is approximately 590 meters. So, we would chose option C: 590.
