Detailed Solution

Given that some migratory birds travel as much as 15000 km to escape the extreme climatic conditions at home.
We need to find the distance in meters in scientific notation form.
Multiply 15000 with 1000 to convert km into m.
15000 km = 15000

\times

1000 m.
15000 km = 15000000 m.
Rewrite 15000000 as the product of 1.5 and 10000000.
15000 km = 1.5

\times

10000000 m
Rewrite 10000000 as 10⁷ to convert into scientific notation.
15000 km =

1.5 \times 10^{7}

.
Scientific notation is

1.5 \times 10^{7}

.
Hence, the correct option is 1.
