Answer:
v = 660 miles per hour
Explanation:
Given that,
The distance covered by the airplane is 1650 miles
Time taken by airplane is 2 hours 30 minutes
We need to find the average speed of the airplane. The total distance covered divided by total time taken is called the average speed of an object.
We know that,
1 hour = 60 minutes
⇒ 30 minutes = 0.5 hour
So,
Hence, the average speed of the airplane is 660 miles per hour.
