Question

a tornado siren begins blaring from the center of town 9.5 seconds after a tornado was spotted. the siren is located 490 meters north of a school. if the siren’s sound wave travels at a constant velocity of 350 meters per second south, how long will it take the sound wave to travel from the siren to the school? write your answer to the tenths place. seconds

Explanation:

Step1: Recall the formula for time

The formula relating distance \(d\), velocity \(v\), and time \(t\) is \(t=\frac{d}{v}\). Here, the distance \(d = 490\) meters and the velocity \(v=350\) meters per second.

Step2: Substitute the values into the formula

Substitute \(d = 490\) and \(v = 350\) into the formula \(t=\frac{d}{v}\). So \(t=\frac{490}{350}\).

Step3: Calculate the value

\(\frac{490}{350}=1.4\) (after performing the division: \(490\div350 = 1.4\)).

Answer:

1.4
