Some migratory birds travel as much as 15000 km to escape the extreme

1.	Some migratory birds travel as much as 15000 km to escape the extreme climatic conditions at home. Write the distance in metres using scientific notation.
Answer» The distance travelled by birds = 15,000 km ∵ 1 km = 1000 m ∴ 15,000 km = 15000 × 1000 m = 15000000 m = 15 × 10⁶ m = 1.5 × 10⁷ m ∴ The distance in metres is 1.5 × 10⁷ m

Answer»

The distance travelled by birds = 15,000 km

∵ 1 km = 1000 m

∴ 15,000 km = 15000 × 1000 m

= 15000000 m

= 15 × 10⁶ m

= 1.5 × 10⁷ m

∴ The distance in metres is 1.5 × 10⁷ m
