Let's take a look at something here. I thought the 15 mph for a base runner was kind of slow. I mean, it was a heck of lot faste

frozen [14]

Answer:

The speed is 20.70 mph.

Explanation:

Given that,

Speed = 6.7 m/s = 15 mph

$1\ m/s = \dfrac{15}{6.7}$

$1 m/s =2.24\ mph$

In 10.4 m/s,

$10.4\ m/s=2.24\times10.4\ mph$

$10.4\ m/s=23.3\ mph$

If 100 m record in 10.82 sec

We need to calculate the speed

Using formula of speed

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

Put the value into the formula

$v=\dfrac{100}{10.82}$

$v=9.242\ m/s$

$v=9.242\times2.24\ mph$

$v=20.70\ mph$

Hence, The speed is 20.70 mph.
