Answer:

5500 meters

Step-by-step explanation:

Meters = m

Kilometres = km

We use the general formula,

1 km = 1000 m

Then by using the general formula,

5.5 km = <u> </u><u>?</u><u> </u> m

→ 5.5 km/1 km × 1000 m

→ 5.5 m × 1000 m

→ 5500 m

Hence, the solution is 5500 m.

. William fills 1/3 of a water bottle in 1/6 of a minute. How much time will it
lesantik [10]

Answer:

1/2 minute

Step-by-step explanation:

We can use a ratio to solve

1/3 bottle     1 bottle

1/6 minute    x minutes

Using cross products

1/3x = 1/6 *1

1/3 x = 1/6

Multiply each side by 3

3 * 1/3x = 3 * 1/6

x = 3/6

x = 1/2

1/2 minute
