15,000 feet to kilometers.

Answer 1

Explanation:

15000 ft x 3.048 x 10^-1 m/ ft = 4572 meters = 4.572 km

Answer 2

`\boxed{\tt 15000 feet = 4.572 kilometers}`

Explanation:

We have;

`\tt 1 feet = 3.048*10^(-1) m`

To convert m to km. we have

`\tt 1 m = 10^(-3) km`

`\tt 3.048*10^(-1) m = 3.048*10^(-1) *10^(-3)= 3.048*10^(-4) km`

Therefore,

`\tt 1 feet = 3.048*10^(-4) km`

Now

`\tt 15000 feet = 3.048*10^(-4)*15000 km`

`\boxed{\tt 15000 feet = 4.572 kilometers}`
