Answer:
a) v = 141.9 m/s
b) v = 317.4 miles/h
Explanation:
a) How fast was he moving in meters per second?
![v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s](https://tex.z-dn.net/?f=%20v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B1000%20m%7D%7B7.045%20s%7D%20%3D%20141.9%20m%2Fs%20)
Hence, the jet ski is moving at 141.9 meters per second.
b) How fast was he moving in miles per hour?
Therefore, the jet ski is moving at 317.4 miles per hour.
I hope it helps you!
