Test Case 1 in python for beginners is hidden...correct code?

Question

Hi! I am new to sololearn and just started the "python for beginners" course as an absolute newbie to programming.
In order to complete the first lesson, I need to pass a quick test. When i enter my code and press 'run' to see my result, unfortunately all I get is this text:
"Test Case 1
This test case is hidden".

Why do I not get the result? Now I neither understand, if my answer was correct, nor am I able to uccessfully complete the first lesson as I finnished only 7 of 8 tasks.

Maybe you guys can tell me if my code/answer is right or wrong?

The task:
"You need to calculate the flight time of an upcoming trip. You are flying from LA to Sydney, covering a distance of 7425 miles, the plane flies at an average speed of 550 miles an hour.
Calculate and output the total flight time in hours.
The result should be a float.

My answer:
print('7425/550')

Answer 1

Every thing you write in quotes (' ' or " ") becomes a string literal. So it prints a string like 7425/550.

Remove quotes, it should be just:

print(7425/550)

Answer 2

thank you so much, guys!
