Question

11 bella is riding her motorcycle directly south. in 2 minutes, she covers 600 meters of distance. what is her velocity?
5 m/s
-5 m/s
-0.2 m/s
300 m/s

Explanation:

Step1: Convert time to seconds

Since \(1\) minute \( = 60\) seconds, \(t=2\) minutes \(=2\times60 = 120\) seconds.

Step2: Use the velocity formula

Velocity \(v=\frac{d}{t}\), where \(d = 600\) meters (distance) and \(t = 120\) seconds (time). Also, assume south - direction as negative.
\(v=\frac{- 600}{120}\) (negative sign for south - direction)
\(v=-5\) m/s

Answer:

\(-5\) m/s (the second option)
