Question

what is the average speed of a cheetah that sprints 100m in 4sec ? what if it sprints 50m in 2sec ?(25m/s)​

Answer 1

Explanation:

HERE IS YOUR ANSWER

Average Speed= TOTAL DISTANCE/ TOTAL TIME

= 100m/4sec

= 25m/s

If It Sprints 50m In 2 Sec then also the answer would be same see

= 50/2 = 25m/sec

Answer 2

➭ Question :-

$\longrightarrow$what is the average speed of a cheetah that sprints 100m in 4sec ? what if it sprints 50m in 2sec ?

➭ Given :-

$\longrightarrow$Distance = 100m

$\longrightarrow$Time = 4sec

➭ To find :-

$\longrightarrow$the average speed of a cheetah

➭ Formula required:-

$\longrightarrow$$\boxed{\sf average \: speed = \frac{Total distance}{total time} }$

➭ Solution :-

$\longrightarrow \rm average \: speed = \frac{total \: distance}{total \: time} \\ \\ \longrightarrow \rm \cancel \frac{100}{4} = 25m/s \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

If it sprints 50m in 2sec

$\longrightarrow \rm average \: speed = \cancel \frac{50}{2} = 25m/s$

Hence,the average speed of the cheetah is 25m/s

=========================

→ MoRe to know....

• The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.
• It's a scalar quantity which means it is defined only by magnitude. A related concept, average velocity, is a vector quantity.
• A vector quantity is defined by magnitude and direction.
