Answer:
friend 5's time = 15 min 24 sec
Step-by-step explanation:
Total time = friend 1's time +friend 2's time + friend 3's time +friend 4's time + friend 5's time
(16*60) s = 9.8s + 5.9s + 9.79s + 9.81s + friend 5's time
960 = 35.3s + friend 5's time
friend 5's time = 960 - 35.3 = 924.7 seconds = 15 min 24 sec
