High amplitude sound would be music, radio, or earthquakes.

Actually Welcome to the Concept of the Kinematics.
1.) Distance travelled = 15+20 = 35 miles.
Ai the total distance covered is 35 miles.
2.) Displacement is the shortest distance from the initial point to the final point.
here it's ==> 20-15 = 5 miles
hence, displacement = 5 miles
Power = (voltage) x (current)
Power = (120) x (8) = 960 watts = <em>0.960 kilowatt</em>
