#we write one function km_to_mile that has
#one parameter the amount of kilometers and prints the correspondent
#number of miles
#use the formula
#miles = km * 0.6214

#write a main that ask tree people to enter distance in km
#and find the distance in miles

CONVERT  = 0.6214

	print(CONVERT*km)

	distance2 = float(input("enter second distance "))
	distance3 = float(input("enter third distance "))

	#function calls:
	
	print("miles for distance 1 ")
	km_to_mile(distance1)

	print("miles for distance 2 ")
        km_to_mile(distance2)

 	print("miles for distance 3 ")
