To calculate the whale's average speed, we need to know the distance traveled.
Let's assume the whale swims straight up from its initial depth of 15 meters to the surface. The distance traveled is the difference between its initial depth and the surface level, which is 15 meters.
Now we can calculate the average speed. The formula to calculate average speed is:
Average speed = Distance/Time
Given that the distance traveled is 15 meters and the time taken is 9.5 seconds, we can substitute these values into the formula:
Average speed = 15 meters / 9.5 seconds
Calculating this:
Average speed = 1.5789 meters/second
Therefore, the average speed of the whale as it swims up to the surface is approximately 1.5789 meters per second.
A whale is swimming at a current depth of 15 meters below the surface. It swims up toward the surface and arrives there 9.5 seconds later.
