Question

An aeroplane travelled 4320 km in 6 hrs. find his speed in m/s?

Answer 1

the speed of aeroplane in 1hr = 4320/6
=720km/hr
speed of aeroplane in m/s. =720*15/8
=1350 m/s

Answer 2

Given :

An aeroplane traveled 4320 km in 6 hrs.

To Find :

find his speed in m/s?

Solution:

Distance traveled by aeroplane = 4320 km

1 km = 1000 m

SO, 4320 km = 4320000 m

So, Distance traveled by aeroplane = 4320000 m

Time taken = 6 hours

1 hour = 3600 seconds

6 hours = $3600 \times 6=21600$

Time in seconds = 21600

Speed in m/sec =$\frac{distance}{Speed}=\frac{4320000}{21600}=200 m/sec$

Hence the speed is 200 m/sec
