Answer 2

Answer:

A person ran by the speed is $0.67 m/s$ or $2.4 km/h.$

step-by-step explanation:

Are using the speed formula, s = d/t, which states that speed is equal to length divided by time, to solve for speed or rate. Use the time equation, t = d/s, which states that time is equivalent to distance multiplied by speed, to solve for time. Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to determine the units for speed.

The overall distance travelled in a specific amount of time is referred to as speed.

$s=\frac{d}{t}$

$s = speed$

$d = distance$

$t = time$

A $4.8$ kilometre runner covered the distance in $7200 seconds.$

total distance travelled $= 4.8 km$

total time $= 7200 sec$

                $=\frac{7200*1}{60*60}$

                $= 2 hours$

$speed=\frac{total distance}{total time}$

        $=\frac{4.8}{2}$

        $= 2.4 km/h$

in m/s:

   $=\frac{2.4*5}{18}$

   $= 0.67 m/s$

Hence the speed is $0.67m/s$  $or$  $2.4 km/h$
