According to the special theory of relativity, all laws of nature are the same in reference frames a. that move at constant speeds. b. that accelerate. c. that vibrate. d. that oscillate. e. none of the above

According to the special theory of relativity, all laws of nature
are the same in reference frames that move at constant speeds. 

That means that there's no test or measurement you can do to
detect whether you're moving at a constant speed or how fast. 
And THAT means that there's no such thing as "who's REALLY
moving" and "who's REALLY at rest".  There's no such thing as
"real" motion, only motion relative to something else.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
