Kilometres and Metres
What are kilometre (kilometer) and metre (meter)?
Kilometre (km) is another unit of length. We use kilometre to measure long distances.
1 km = 1000 m
Or,
1000 m = 1 km
1 km = 1000 m
Or,
1000 m = 1 km
1. Richard visited his grandmother who lives 1 km 630 m away from his house.
Express this distance in metres.
We know,
1 km = 1000 m
Hence,
1 km 630 m
= 1 km + 630 m
= 1000 m + 630 m
= 1630 m
The distance is 1630 m.
1 km = 1000 m
Hence,
1 km 630 m
= 1 km + 630 m
= 1000 m + 630 m
= 1630 m
The distance is 1630 m.
2. What is 7 km 90 m in metres?
We know,
1 km = 1000 m
So,
7 km = 7000 m
Hence,
7 km 90 m
= 7 km + 90 m
= 7000 m + 90 m
= 7090 m
1 km = 1000 m
So,
7 km = 7000 m
Hence,
7 km 90 m
= 7 km + 90 m
= 7000 m + 90 m
= 7090 m
3. Stephanie is going to the mall.
The mall is 4059 m away.
What is this distance in kilometres and metres?
We know,
1000 m = 1 km
So,
4000 m = 4 km
Hence,
4059 m
= 4000 m + 59 m
= 4 km + 59 m
= 4 km 59 m
The distance is 4 km 59 m.
1000 m = 1 km
So,
4000 m = 4 km
Hence,
4059 m
= 4000 m + 59 m
= 4 km + 59 m
= 4 km 59 m
The distance is 4 km 59 m.
