A family is on a road trip. The speed limit during the first 145 miles of the trip is 60 mph, and the speed limit during the last 190 miles is 65 mph. How many miles per hour over the speed limits must they drive in
order to arrive at their destination in 5 hours?

it’s supposed to be -4+45=41

step-by-step explanation:

dude thats to long figure it

step-by-step explanation:

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)
