For lab 1D we will be using an ultrasonic sensor. This works by emitting a sound wave from a speaker and bouncing it off an object. The delay between the sending and retrieval of this sound wave allows us to determine the distance to the object. Assuming a speed of sound of 343 m/s, answer the questions below.

How far does a sound wave travel in 3000 microseconds? (Give your answer in centimeters)

How long does it take for a sound wave bounce off an object 50 centimeters away and return? (Give your answer in microseconds, rounded to the nearest 0.1 s)

Complete all your calulations in python and show your work below.
