Cheetah

Cheetah elapse 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).

Result

g =  30 m/s
o =  63.889 m/s
d =  20 m/s

Solution:

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

$o=230 \cdot \ 1000/3600=\dfrac{ 575 }{ 9 } \doteq 63.8889 \doteq 63.889 \ \text{m/s}$

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