Question

if you know the r departure and arrival time of a certain flight ( which you can find from the flight information to the internet) you can calculate the average speed of an aeroplane by dividing the distance between two points time taken to cover them. calculate the speed average speed of any five aeroplane. work in groups.​

Answer 1

Answer:

Step-by-step explanation:

The first aeroplane leaves an airport and flies due north at a speed of 1000 km per hr.

∴ Distance travelled in 1.5 hrs.

=1000×1.5=1500 km

Similarly, Distance traveled by second aeroplane,

=1200×1.5=1800 km

In △ABC,

BC is distance travelled by first aeroplane and BA is the distance traveled by second aeroplane.

Hence, applying Pythagoras Theorem,
