The height of the cone is 4 cm (approx).
Step-by-step explanation:
Given,
The radius (r) of the cone = 4.96 cm
Volume (V) = 102 cm³
To find the height (h) of the cone.
Formula
The volume of a cone V =
πr²h
Now,
According to the problem,
πr²h = 102
or,
×
×(4.96)²h= 102
or, h = 
or, h = 3.95 = 4 (approx)
so,
Height = 4 cm (approx)
5% of 120 is 6
120 - 6 = 114
Her time would be reduced to 114 seconds.

8 miles in 40 minutes = 12 miles per hour
5 miles in 30 minutes = 10 miles per hour
workings
60/40=1.5
1.5x8=12
60/30=2
2x5=10
method
you divide the 60 by however many minutes, then times that by the amount of miles
