Question
A humpback whale swam south at a constant velocity for 45minutes. In one-third of that time, it swam 3,510meters. What was the whale's velocity?
Solution
Sure, let's solve this step by step:
-
First, we need to find out how long is one-third of 45 minutes. To do this, we divide 45 by 3, which gives us 15 minutes.
-
We know that in 15 minutes, the whale swam 3,510 meters.
-
Velocity is defined as the distance traveled divided by the time taken. In this case, the distance is 3,510 meters and the time is 15 minutes. However, velocity is typically measured in meters per second, not meters per minute. So we need to convert 15 minutes to seconds. There are 60 seconds in a minute, so 15 minutes is 15 * 60 = 900 seconds.
-
Now we can calculate the velocity by dividing the distance by the time: 3,510 meters / 900 seconds = 3.9 meters per second.
So, the whale's velocity was 3.9 meters per second.
