Answer :
It was a constant velocity over 9.6 seconds so it’s speed was 72/9.6 or 7.5m/s
A barracuda swam directly toward a coral reef at a speed of 9.6 seconds. It swam 72 meters. so its speed was 7.5m/s.
What is speed?
Speed can be calculated as the ratio of distance traveled to the time taken.
Speed = Distance/ time taken
A barracuda swam directly toward a coral reef at a constant velocity for 9.6 seconds. It swam 72 meters in that time.
Distance = 72 meters
Time taken = 9.6 seconds
So,
Speed = Distance/ time taken
Speed = 72/ 9.6
= 720/ 96
= 7.5m/s
