Question

It takes 19 and a half hours to fly the 14418 km

trip from Cario to Sydney. What is the average


speed of the airplane?

Answer 1

To calculate the average speed of the airplane flying from Cairo to Sydney, we can use the formula:

Average speed = Distance ÷ Time

In this case, the distance is 14,418 km and the time is 19.5 hours.

So, the average speed of the airplane would be:

Average speed = 14,418 km ÷ 19.5 hours

Average speed = 739.38 km/h

Therefore, the average speed of the airplane flying from Cairo to Sydney is approximately 739.38 km/h.

Answer 2

Answer ≈ 739.38 km/h

Explanation:

Step 1: Convert the time from hours and minutes to hours and decimals

19 and a half hours is the same as 19.5 hours. This is because half an hour is equal to 0.5 of an hour.

Step 2: Calculate the average speed

Average speed is equal todistance traveled divided by time taken:

`\LARGE \boxed{\textsf{Average Speed = $\frac{\textsf{Distance}}{\textsf{Time}}$ }}`

The distance from Cairo to Sydney is 14,418 km, and the time taken is 19.5 hours. So, we can substitute these values into the formula:

`\Large \boxed{\begin{minipage}{14.05 cm}Average Speed = $\frac{\text{14418 km}}{\text{19.5 hours}}\\ \\\text{Average Speed = 739.38 km/hours (rounded to 2 decimal places)}\end{minipage}}`

Therefore, the average speed of the airplane flying from Cairo to Sydney is approximately 739.38 km/hour.
