So the difference between 6:00 am and 7:16 am is 1 hour and 16 minutes, which can be converted into 76 minutes. 76 is not a multiple of 9, so you have to find the closest which is 81. 81 - 76 = 5, so you have to wait 5 minutes for a bus. I hope this helps! Let me know if you have any questions or anything :)
