Speed=0.3*100=30m/s

speed=0.1*50=5m/s

frequency=20/0,5=40HZ

frequency=80/0.2=400HZ

frequency=120/0.4=300HZ

wavelength=340/440=0.77m

wavelength=340/880=0.39m

wavelength=250/400=0.63m

speed=2*50=100m/s

speed=0.5*100=50m/s

Answer from: Quest

Answer: it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.explanation: we have equation of motion $s=ut+\frac{1}{2} at^2$ ,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/s $s=0*t+\frac{1}{2} *2.18*t^2$ $s=1.09t^2[/ 2equating equation 1 and 2 [tex]4.75t = 1.09t^2\\ \\ t=4.36 seconds.$ so it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.
