Cheetah

The cheetah elapses 150 m for 5 seconds, the eagle reaches speeds up to 230 km/h, and the dolphin swims 1.2 km per minute. Which animal is the fastest and slowest? The results are written as meters per second (m/s).

Final Answer:

g =  30 m/s
o =  63.8889 m/s
d =  20 m/s

Step-by-step explanation:

$$\begin{gathered} s_1=150\text{m} \\ {t}_1=5\text{s} \\ g=s_1/t_1=150/5=30\text{m/s} \end{gathered}$$

$o=230\text{km/h}\to \text{m/s}=230:3.6\text{m/s}=63.889\text{m/s}=63.8889\text{m/s}$

$$\begin{gathered} s_3=1.2\text{km}\to \text{m}=1.2\cdot 1000\text{m}=1200\text{m} \\ {t}_3=1\text{min}\to \text{s}=1\cdot 60\text{s}=60\text{s} \\ d=s_3/t_3=1200/60=20=20\text{m/s} \\ o>g>d \\ 1.eagle/orol \\ 2.cheetah/gepard \\ 3.dolphin/delfin \end{gathered}$$
