The speed of a sound wave
is slower than an electromagnetic wave
is faster than an electromagnetic wave
is equal to an electromagnetic wave
cannot be measured

I think the correct answer from the choices listed above is the first option. The speed of a sound wave is slower than an electromagnetic wave or light waves are faster than sound waves. Hope this answers the question. Have a nice day.

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.
