Answer:
99000 meters.
Explanation:
We have the swimmer going at 50 m / s, and we want to know where he is going in 33.3 minutes.
The first thing is to pass the time from minutes to seconds, we know that 1 minutes is 60 seconds, therefore:
33.3 min * 60 s / 1 min = 1998 seconds
Now to know the distance is to multiply this time by the speed they give us, like this:
1998s * 50m / s = 99900 m
Which means that in that time and at the speed of the swimmer, he has traveled 99000 meters.
