Question

A football player runs down a field with a speed of 8 m/s. How long will it take him to run 20m?

Answer 1

To find the answer for this question, you simply need to divide 20 by 8, which is the speed he is traveling. 

20 / 8 = 2.5

The football player will run 20 yards in 2 1/2 seconds.
Hope that helped! =)

Answer 2

Answer:

Time taken, t = 2.5 seconds

Explanation:

It is given that,

Speed of the football player, v = 8 m/s

We have to find time taken by the football player to run 20 m. It can be calculated suing the formula of speed of the player i.e.

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

d = distance

t = time taken

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

$t=\dfrac{20\ m}{8\ m/s}$

t = 2.5 seconds

Hence, time taken by the football player is 2.5 seconds
