Question

What is the speed of a cheetah that travels 176.4 meters in 4.5 seconds?

Answer 1

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

Step-by-step explanation:

Given,

Distance travelled ( d ) = 176.4 meters

Time taken ( t ) = 4.5 seconds

Finding the speed of a cheetah

Speed
`\sf{ = (distance \: travelled)/(time \: taken) }`

`\sf{ = (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 = (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.
