Conversion of Metres into Kilometres

Example : Convert into kilometres.

a. 3402 m b. 9268 m

Solution : a. 3402 m = 3000 m + 402 m

\ 1 km = 1000 m
= (3000 ÷1000) km + 402 m

= 3 km + 402 m

= 3 km 402 m

b. 9268 m = 9000 m + 268 m

\ 1 km = 1000 m

= (9000 ÷ 1000) km + 268 m

= 9 km + 268 m

= 9 km 268 m
