This problem is incomplete, I think the figure is needed. Assuming that the figure I found is correct, therefore the distance we need to walk from room 103 to 117 is:
distance = 86 ft – 22 ft = 64 ft
We can calculate for time using the formula:
time = distance / speed
time = 64 ft / (4.4 ft / second)
time = 14.55 seconds
