To find the barracuda's velocity, you can use the formula for velocity:
Velocity (v) = Distance (d) / Time (t)
In this case, you are given the time and distance, so you can calculate the velocity.
Given:
Time (t) = 28 seconds
Distance (d) = 35 meters (swam 35 meters in one-quarter of the time, which is 28 seconds / 4 = 7 seconds)
Now, use the formula to calculate the velocity:
Velocity (v) = Distance (d) / Time (t)
v = 35 meters / 7 seconds
v = 5 meters per second
So, the barracuda's velocity is 5 meters per second.
