Question

A shark travels with an average velocity of 12 m/s s. How long (time) would it take the shark to swim 42 m at that velocity

Answer 1

Answer:

t=3.5 seconds

Explanation:

Moving at Constant Speed

Let's suppose and object travels in a constant direction and covers the same distances x at the same time t, we say it has a constant speed. It can be computed as:

$\displaystyle v=\frac{x}{t}$

The time taken to go through the distance x is computed by

$\displaystyle t=\frac{x}{v}$

Our shark moves at v=12 m/s and we need to compute the time it takes to swim x=42 m, so we have

$\displaystyle t=\frac{42}{12}$

$\boxed{t=3.5\ seconds}$

It takes the shark 3.5 seconds to swim 42 m
