Using python 3.0 or greater. I need help writing this recursive function.

Question: Write a recursive function (not using loops, global varibles, or other ways to go around using a simple recursion) to calculate the time it takes to travel a certain distance.

The conditions are:

If the distance is 1m or less, then it takes 1 min to travel.

If the distance is greater than 1m, then every step is half the distance until it is equal or less than 1m for 1 min each step. Then the last step would take 1min to travel.

Ex. distance= 10m

10/2= 5m (+1min), 5/2 =2.5m (+1min), 2.5/2= 1.25 (+1min), 1.25/2= 0.625 (+1min), 0.625 to the end (+1min).

total time= 1+1+1+1+1= 5min to travel.

To see if the recursion is correct here is another example for the correct output (537m will take 11minutes).

This is the work I completed so far. I am having trouble writing the recursive case.

def time_travelled(distance): """   :param distance: distance to travel  :return: Total time it takes to travel the distance entered.  """   if distance<=1: return 1 else: return time_travelled(distance-1)/2 

print(time_travelled(5))

0.0625

 print(spaceTime(28))
