Question

1. monissa is skateboarding on a straight stretch of sidewalk. in 3.0 minutes, she travels 486 meters. what is the magnitude of her velocity during this stretch? 0.37 m/s 162 m/s 2.7 m/s 8.1 m/s

Explanation:

Step1: Convert time from minutes to seconds

Since \(1\) minute \( = 60\) seconds, then \(t=3.0\) minutes \(=3.0\times60 = 180\) seconds.

Step2: Use the velocity formula \(v=\frac{d}{t}\)

Given \(d = 486\) meters and \(t = 180\) seconds. Substitute into the formula: \(v=\frac{486}{180}\).
Calculate \(\frac{486}{180}=2.7\) m/s.

Answer:

\(2.7\) m/s (the third option)
