    Answer:

     \boxed{ \bold{ \boxed{ \sf{39.2 \: m/ {s} \:  }}}</strong><strong>}</strong><strong>

    Explanation:

    Given,

    Distance travelled ( d ) = 176.4 meters

    Time taken ( t ) = 4.5 seconds

    Finding the speed of a cheetah

    Speed  \sf{ =  \frac{distance \: travelled}{time \: taken} }

     \sf{ =  \frac{176.4}{4.5} }

     \sf{ = 39.2 \: m/ {s} \:  }

    ————————————————————————

    Let’s learn about Speed :

    Suppose a body moves 20 m in 2 seconds, either on a curved path or on a straight path. So , 10 m is the distance travelled by the body in each second which can be written as 10 m/s. This is called speed of the body. Thus, Speed is defined as the distance travelled per unit time. It is the rate of distance travelled by a body.

    Mathematically,

     \boxed{ \bold{ \sf{speed =  \frac{distance \: travelled}{time \: taken} }}}

    In SI system, the unit of distance is metre and time is second. Thus , the SI unit is speed is m/s.

    Hope I helped!

    Best regards!!
