Question

A spaceship travels 72000 km in one hour. Express its speed in km/s​

Answer 1

Step-by-step explanation:

Spaceship speed is 72000 km/h

So, in 1 hour spaceship travel 72000 km

Or we can say that in 60×60 second spaceship travel

72000 km

= 72000/60×60

you cut all 0 because 0 has no value

it will be 72/36

72 and 36 came in 18 table so cut this and in the place of 72 write 4 and in the class of 36 write 2 because 18×4 =72 and 18×2 = 36

= 18km/s
