99.45 should be your answer
If you want me to show work let me know
12/3 is 4 breaks 12x60 is 720mins at most with 4x20= 80 = 720-80=640/ 60 means we have 10.67 hours left 550/10.67= 51.55 mph
If you would like to solve the system of equations 2r + 2s = 50 and 2r - s = 17, you can do this using the following steps:
<span>2r + 2s = 50
2r - s = 17 ... 2r = 17 + s
</span>____________
<span>2r + 2s = 50
</span>17 + s + 2s = 50
17 + 3s = 50
3s = 50 - 17
3s = 33
s = 33/3
s = 11
<span>2r = 17 + s = 17 + 11 = 28
</span>2r = 28
r = 28/2
r = 14
(r, s) = (14, 11)
The correct result would be <span>d. r = 14, s = 11.</span>
