8

and divide 72 by 8

It will take her 9 hours.

Step-by-step explanation:

Divide 48 by 6.

8

and divide 72 by 8

Step-by-step explanation:

Divide 48 by 6 = 8

Divide 72 by 8 = 9

It will take her 9 hours.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
