Question

a barracuda swam directly toward a coral reef at a constant velocity for 20 seconds. in one - quarter of that time, the barracuda swam 30 meters. what was the barracudas velocity? write your answer as a whole number. meters per second directly toward the reef

Explanation:

Step1: Calculate the total distance

The barracuda swam 30 meters in one - quarter of the time (20 seconds). So the total distance \(d\) it would swim in 20 seconds is \(d = 30\times4=120\) meters.

Step2: Calculate the velocity

The formula for velocity \(v\) is \(v=\frac{d}{t}\), where \(d\) is distance and \(t\) is time. Given \(d = 120\) meters and \(t = 20\) seconds. Then \(v=\frac{120}{20}=6\) meters per second.
