Question

1. rebecca bought a wind - up car that travels in a straight line. if the cars average velocity was 1.5 m/s south, and it traveled a distance of 18 meters in that direction, how long was the car moving?

19.5 seconds
27 seconds
12 seconds
16.5 seconds

Explanation:

Step1: Recall the formula for velocity

The formula for average velocity \(v\) is \(v=\frac{d}{t}\), where \(d\) is the distance and \(t\) is the time. We need to solve for \(t\), so we can rewrite the formula as \(t = \frac{d}{v}\).

Step2: Substitute the given values

We are given that \(d = 18\) meters and \(v=1.5\) m/s. Substituting these values into the formula \(t=\frac{d}{v}\), we get \(t=\frac{18}{1.5}\).

Step3: Calculate the value of \(t\)

\(\frac{18}{1.5}=12\)

Answer:

12 seconds
