While riding her bike to the ocean and back home 5 times, mandi timed herself at 58min, 54min, 65min, 52min, and 62min. she had set a goal of averaging 60 minutes for her rides. how many minutes will she need to spend on her sixth ride to attain her goal?

69 minutes.

Step-by-step explanation:

For an average of 60 minutes the total time has to be 6*60 = 360 minutes.

So the last ride must take 360 -  (58 + 54 + 65 + 52 + 62)

= 360 - 291

= 69 minutes.

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)
