Answer:
At time t = 0.408 sec diver will be at maximum height
Step-by-step explanation:
We have given equation of the height 
We know that velocity is the rate of change of distance with respect to time
So 
At maximum height velocity will be zero
So 
t = 0.408 sec
So at time t = 0.408 sec diver will be at maximum height
1/8 is greater because say you have 1/8 of a pizza you will get a bigger piece but if you had 5/7 it will be be 5 tiny pieces. so 1/8 is greater than 5/7
