Answer:
![\boxed {\boxed {\sf v\approx0.24 \ m/s}}](https://img.qammunity.org/2021/formulas/physics/high-school/cja52ib38lwl5szvjeks0w1mcoteg2xcmr.png)
Step-by-step explanation:
Velocity can be found by dividing the displacement by the time.
![v=(displacement)/(time)](https://img.qammunity.org/2021/formulas/physics/high-school/h8xkmsy120tnzybypdkgt8zqqfd04h4fdl.png)
The displacement is 4.77 meters and the time is 19.5 seconds.
![displacement=4.77 \ m \\time=19.5 \ s](https://img.qammunity.org/2021/formulas/physics/high-school/t9yvn9sdl370sg1bfl3ky1m8xubs3lfmi8.png)
Substitute the values into the formula.
![v=(4.77 \ m )/(19.5 \ s)](https://img.qammunity.org/2021/formulas/physics/high-school/741kvnocw1ka060nnqv9kiha2g3ea5xpqr.png)
Divide.
![v=0.244615385 \ m/s](https://img.qammunity.org/2021/formulas/physics/high-school/ggw71q86ph5cqhahj5bloecknc74g7nx5y.png)
Let's round to the nearest hundredth (just to make the answer more concise).
The 4 in the thousandth place tells us to leave the 4 in the hundredth place.
![v\approx0.24 \ m/s](https://img.qammunity.org/2021/formulas/physics/high-school/s6b52gsc1676y5d41pvarwgxgovpao7fig.png)
The velocity of the turtle is about 0.24 meters per second.
