some please help me !

anonymous · Answer

a) 14 cups if my working out is correct.

anonymous · Answer

1hour = 4x15min
so 3hours = 3x4x15min=12 cups and then u had another 15 min to complete the race + the 2 cups before the race which gives us: 12+1+2= 15 cups of water

anonymous · Answer

F=Cups
N=every 15minutes interval
M=the starting Cups

So, F=N+M
So if i run for an hour, 60min, which is 4 N's i will drink: F=4+2 -> 6 cups
