Question

Convert falloing units as indicates

a) 500cm---m b)1km ---m
c) 4000m ---km d) 2hr minute e)2tone ---kg
​

Answer 1

1 cm= 1/100 m

So, (a) 500 cm= 1/100×500//1=5 metres

(b) 1 km=1000m

(c) 1 m=1/1000 km

So, 4000m=1/1000×4000/1=4 km

Answer 2

a. 5 meters

b. 1000 meters

c. 4 kilometers

d. 120 minutes

e. 2000 kilograms

Step-by-step explanation:

Let's convert the units as indicated:

`a) \(500 \, \text{cm} \rightarrow \text{m}\)`

To convert centimeters to meters, you divide by 100 (since 1 meter = 100 centimeters):

`\[ 500 \, \text{cm} = (500)/(100) \, \text{m} = 5 \, \text{m} \]`

b)
`\(1 \, \text{km} \rightarrow \text{m}\)`

To convert kilometers to meters, you multiply by 1000 (since 1 kilometer = 1000 meters):

`\[ 1 \, \text{km} = 1 * 1000 \, \text{m} = 1000 \, \text{m} \]`

c)
`\(4000 \, \text{m} \rightarrow \text{km}\)`

To convert meters to kilometers, you divide by 1000:

`\[ 4000 \, \text{m} = (4000)/(1000) \, \text{km} = 4 \, \text{km} \]`

d)
`\(2 \, \text{hr} \rightarrow \text{minutes}\)`

To convert hours to minutes, you multiply by 60 (since 1 hour = 60 minutes):

`\[ 2 \, \text{hr} = 2 * 60 \, \text{minutes} = 120 \, \text{minutes} \]`

e)
`\(2 \, \text{ton} \rightarrow \text{kg}\)`

To convert tons to kilograms, you multiply by 1000 (since 1 ton = 1000 kilograms):

`\[ 2 \, \text{ton} = 2 * 1000 \, \text{kg} = 2000 \, \text{kg} \]`

So, after conversion:

a)
`\(500 \, \text{cm} = 5 \, \text{m}\)`

b)
`\(1 \, \text{km} = 1000 \, \text{m}\)`

c)
`\(4000 \, \text{m} = 4 \, \text{km}\)`

d)
`\(2 \, \text{hr} = 120 \, \text{minutes}\)`

e)
`\(2 \, \text{ton} = 2000 \, \text{kg}\)`
