Answer»

Answer:

27000 मीटर चलेगी

Explanation:

81 kilometres PER hour

In one hour 60 minutes

so we need to find how much it will TRAVEL in 20 minutes so just divide 60 ÷ 20 , and you will get 3

Now , divide 81 by 3 and u will get 27 and now TURN 27 kilometres into METER and you will get 27000 .

Therefore, 27000 meters is the correct answer
