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

t=3.5 seconds

Step-by-step 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=(x)/(t)`

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

`\displaystyle t=(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=(42)/(12)`

`\boxed{t=3.5\ seconds}`

It takes the shark 3.5 seconds to swim 42 m
