Question

Which of the following distances is the shortest? 0.007 km 0.2 cm 30 mm 580 mm

Answer 1

Answer: Option (b) is the correct answer.

Step-by-step explanation:

Since, all the given distances are present in different units. So, convert them into same unit.

As there are 1000 meter present in 1 kilometer so, we convert all of them into meter as follows.

`0.007 km * (1000 m)/(1 km)`

= 7 m

There are 0.01 m present in 1 cm.

So,
`0.2 cm * (0.01 m)/(1 cm)` = 0.002 m

There are 0.001 m present in 1 mm.

So,
`30 mm * (0.001 m)/(1 mm)` = 0.03 m

`580 mm * (0.001 m)/(1 mm)` = 0.58 m

Thus, we can conclude that out of the given options shortest distance is 0.2 cm.
