Question
If Raju travels 3 km everyday, then how many centimetres does he travel everyday?
Answer: Option B
:
B
When we convert a larger unit (km) to a smaller unit (m), we multiply the given measure by the conversion factor.
Since 1 km = 1000 m, we multiply 3 by 3000 to convert 3 kms into metres.
i.e., 3km = 3 x 1000 m = 3000 m
To convert metres into centimetres, we multiply the given measure by 100.
i.e., 3000 m = 3000 x 100 cm = 300000 cm
Thus, Raju travels a total of 300000 cm everyday.
