Hello. I have this code in python it runs well, however, I have a problem with the following question.

" Not quite. Remember to use the str() function to convert numbers into strings when printing them with text, and to call the function with just one parameter, then accept the return value into a new variable."

i tried to add str(55) but still could not figure it out. so need help with that.

def convert_distance(miles):

return 1.6 * miles

print("The distance in kilometers is ", convert_distance(55))

print("The round-trip in kilometers is ", convert_distance(2*55))
