Calculating Distance and Average Speed of a Helicopter
How much total distance did the helicopter cover?
1.37x10^2 km
If the total flight time of the helicopter was 42.0 minutes, then what was the average speed of the helicopter?
Options:
- A. 185.71 km/h
- B. 195.71 km/h
- C. 205.71 km/h
- D. 215.71 km/h
Answer:
Final answer: The average speed of the helicopter is 195.71 km/h.
The helicopter covers a total distance of 1.37x10^2 km from the accident site to the hospital and then back to its base. To calculate the average speed of the helicopter, we need to consider the total distance covered and the total flight time.
Firstly, the total distance covered by the helicopter is 1.37x10^2 km. Secondly, the total flight time is given as 42.0 minutes. We need to convert this time into hours by dividing it by 60, which gives us 0.7 hours.
Using the formula for average speed: Average Speed = Total Distance / Total Time, we can substitute the values:
Average Speed = 1.37x10^2 km / 0.7 hours
Solving the calculation, we get an average speed of 195.71 km/h for the helicopter. Therefore, the correct answer to the second question is B. 195.71 km/h.
Calculating the average speed of a helicopter is important to ensure efficient and safe transportation of patients from accident sites to hospitals. Understanding the principles of distance and time in relation to speed helps in determining the best course of action during emergency situations.
