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.
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.
To determine the whale's average upward speed, we need to know the distance it traveled.
First, we need to calculate the distance the whale traveled from its initial depth of 15 meters below the surface to the surface. We know that the whale's average speed is the distance traveled divided by the time it took.
Let's assume that the whale's speed remains constant during its ascent.
The formula for calculating distance is:
Distance = Speed × Time
Since the whale starts at a depth of 15 meters and ends at the surface, the distance it traveled is 15 meters.
We can now calculate the whale's average upward speed.
Average Upward Speed = Distance ÷ Time
Average Upward Speed = 15 meters ÷ 9.5 seconds
Average Upward Speed ≈ 1.58 meters per second
Therefore, the whale's average upward speed is approximately 1.58 meters per second.
To determine the speed of the whale, we can use the formula: speed = distance/time.
First, we need to find the distance the whale traveled from its initial depth to the surface. We know that the whale started at a depth of 15 meters below the surface. When it reaches the surface, its depth will be zero meters. Therefore, the distance traveled is:
distance = 15 meters - 0 meters = 15 meters
Next, we need to find the time it took for the whale to reach the surface. We are given that it took 9.5 seconds.
time = 9.5 seconds
Now, we can calculate the whale's speed:
speed = distance/time = 15 meters / 9.5 seconds = 1.58 meters/second
Therefore, the whale is swimming at a speed of 1.58 meters per second.
