2/3 of a hippo's life is spent under water, the rest of their life out of water is separated into grazing, sleeping, and socialising in the ratio of 4 : 7 : 1. the average life of a hippo is 45 years, how long will it spend doing each of these activities?

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
