Question

what is the average speed of a cheetah that sprints 100m in 4s what if it sprints 50m in 2sec

Answer 1

Explanation:

both ans are same

please atleaset make this as brainlist

Answer 2

AVERAGE SPEED IN BOTH CASES IS 25 m/s.

Given:

• Cheetah goes 100 metres in 4 seconds.
• It also goes 50 metres in 2 seconds.

To find:

Average speed in both case ?

Calculation:

Average speed is defined as the total distance divided by the total time taken to travel.

In 1st case:

$avg. \: v = \dfrac{total \: distance}{total \: time}$

$\implies avg. \: v = \dfrac{100}{4}$

$\implies avg. \: v = 25 \: m {s}^{ - 1}$

Now, in 2nd case:

$avg. \: v = \dfrac{total \: distance}{total \: time}$

$\implies avg. \: v = \dfrac{50}{2}$

$\implies avg. \: v = 25 \: m {s}^{ - 1}$

So, in both cases , the average speed is 25 m/s .
