Question

A trip to Cape Canaveral, Florida takes 10 hours. The distance is 816 km. Calculate the average speed​

Answer 1

Answer:

Speed = 81.6 km/hr

Explanation:

Speed= Distance/ Time

Speed = 816/ 10

Speed = 81.6 km/hr

Answer 2

Answer:

The average speed of the trip is $81.6\hspace{1mm} km/h$.

Explanation:

• When the total distance of the journey is divided by the total time taken, we get the average speed.
• The speed of the body may be changing during the journey so, the average speed is important.

The formula for the average speed is:

$Average$ $Speed =\frac{D}{T}$

where  $D$ is the total distance of the journey

            $T$ is the total time taken.

The total distance for Cape Canaveral's trip, $D=816$ $km$

Total time of the trip, $T=10$ $hrs$

The average speed $=\frac{816\hspace{1mm} km}{10\hspace{1mm} hrs}$

                                 $=81.6\hspace{1mm} km/h$

So, the average speed of the trip is $81.6\hspace{1mm} km/h$.
