Question

a barracuda can swim at a maximum speed of 28 meters per second. if it is swimming away from a coral reef at one - quarter of its top speed, how far will the barracuda swim in 10 seconds? write your answer as a whole number. meters

Explanation:

Step1: Calculate actual speed

The barracuda swims at one - quarter of its top speed. The top speed is 28 meters per second. So the actual speed $v=\frac{28}{4}=7$ meters per second.

Step2: Calculate distance

We use the formula $d = v\times t$, where $v$ is speed and $t$ is time. Given $v = 7$ m/s and $t = 10$ s. Then $d=7\times10 = 70$ meters.

Answer:

70
