Question

12/12 a helicopter flies west 2500 meters in 120 seconds. what is 20.8 m/s 20.8 m/s west 100.5 m/s south 40.2 m/s

Explanation:

Step1: Recall speed formula

Speed is calculated as \( v=\frac{d}{t} \), where \( d \) is distance and \( t \) is time.

Step2: Substitute values

Here, \( d = 2500\space m \) and \( t = 120\space s \). So \( v=\frac{2500}{120}\approx20.8\space m/s \).

Step3: Determine direction

The helicopter flies west, so velocity (speed with direction) is \( 20.8\space m/s \) west.

Answer:

B. 20.8 m/s west
