Question

A tornado siren sounded from the center of town. The siren's sound wave traveled at 350 meters per second toward a school. At this velocity, how far did the sound wave travel in 2.2 seconds?

A) 770 meters
B) 7700 meters
C) 77 meters
D) 7.7 meters

Answer 1

The siren's sound wave traveled 770 meters in 2.2 seconds.

Step-by-step explanation:

To calculate how far the siren's sound wave traveled in 2.2 seconds, we will use the formula for speed equals distance divided by time (v = d/t). Given that the speed of sound is 350 meters per second, we can rearrange the formula to solve for distance (d = v * t).

Substituting the given values into the equation:

• d = 350 m/s * 2.2 s
• d = 770 meters

Therefore, the siren's sound wave traveled 770 meters in 2.2 seconds.
