To calculate the average velocity of the Westland Lynx helicopter, we can use the formula:
Average Velocity = Total Distance / Total Time
Given that the helicopter travels 3.33 km in 30 seconds, we can convert the time to hours by dividing it by 3,600 (since there are 3,600 seconds in an hour):
Total Time = 30 seconds / 3600 = 0.00833 hours
Plugging the values into the formula:
Average Velocity = 3.33 km / 0.00833 hours ≈ 400 km/h
Therefore, the average velocity of the Westland Lynx helicopter is approximately 400 kilometers per hour.
