Answer:
The average speed was 800 miles/hour
Explanation:
Average Speed
If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:
[tex]\displaystyle V=\frac{d}{t}[/tex]
A plane took 3 hours and 33 minutes to travel d=2840 miles to finish its journey. We will calculate the average speed in miles per hour, thus the time needs to be expressed in hours, and it's given in a mixed unit:
t=3 hours+33 minutes
Since there are 60 minutes in an hour:
t=3 hours+33 /60 hours = 3 hours + 0.55 hours = 3.55 hours
Now calculate the average speed:
[tex]\displaystyle V=\frac{2840}{3.55}=800[/tex]
The average speed was 800 miles/hour
