Question

Quizplus · Accepted Answer

The time it takes for the chirp to travel to the lunch and its echo to return is:

time = 2*distance/speed

where distance is the distance traveled by the chirp and speed is the speed of sound (340 m/s).

We know that the echo is heard 1 s after the chirp, so we can set up an equation:

1 = 2*distance/340

Solving for distance, we get:

distance = 340/2 = 170

Therefore, the distance to the lunch is 170 m.
