Cheetah

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

Correct result:

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

Solution:

$g=150\mathrm{/}5=30\text{ m/s}$

$o=230\cdot 1000\mathrm{/}3600={\displaystyle \frac{575}{9}}=63.8889\text{ m/s}$

$d=1.2\cdot 1000\mathrm{/}60=20\text{ m/s}$
