## 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. 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

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

=

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

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**.
