Question

If the sound wave lasts 4 seconds, how much distance did it travel? (please help me)

Answer 1

Answer:170

Explanation: 0.50

can also be written as

1

.

0.50

seconds is half of a second.

if the wave travels

340

m

every second, it will travel half of that distance in

0.50

seconds.

170

in half of a second, the wave will have travelled

170

metres away from its source.

Answer 2

A wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave moving along the medium (the ocean water), one can observe that the crest of the wave is moving from one location to another over a given interval of time. The crest is observed to cover distance. The speed of an object refers to how fast an object is moving and is usually expressed as the distance traveled per time of travel. In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time. In equation form,If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s. On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds (the same amount of time), then the speed of this ocean wave is 2.5 m/s. The faster wave travels a greater distance in the same amount of time.
