Answer:1) 6400

Explanation: In this, at first we will look at the last 2 digits in 6347..i.e 47 which will be rounded off to 50. So now we get 6350 . Again when we round off 350 tp the nearest 100 3 being an odd number adds up 1 to become 4 and thus 400 which now gives us the final answer 6400km.

Hope it helps
