Question

an aeroplane travelled 4320 km in 6 hr find its speed in km /hr ()m/sec

Answer 1

Answer:

The speed of aeroplane is 720 km/hr

Step-by-step explanation:

Distance travelled = 4320 km

Time taken to cover the distance = 6 hr

we know that,

Speed = distance/time

= 4320 km/ 6 hr

= 720 km/hr

Therefore the speed of aeroplane is 720 km,/hr

Answer 2

Answer: 720 km/hr and 200 m/s

Step-by-step explanation:

Distance covered by the aeroplane - 4320 km

Time aeroplane took to cover 4320 km - 6 hrs

Speed = Distance ÷Time

4320 ÷ 6 = 720

So, the speed in km/hr is 720 km/hr

To convert km/hr into m/s we multiply it by 5 /18

4320/6 × 5/18 = 21600/108

21600/108 in simplest form is 200 m/s

So, the speed in m/s is 200 m/s
