# 9. Write a program in python to ask distance in kilometer and convert into miles.

``````# Program to ask distance in kilometer and convert into miles
"""
In this program, we have to calculate the miles when kilometer is given
We have the formula,
miles = kilometer*0.62
To calculate this  we have to ask the distance in kilometer

k = float(input('enter the distance in kilometer'));
mile=k*0.62

If the values are explicitly given.
Then we do not have to ask the values from the user
