Answer:
Step-by-step explanation:
Bus One
speed = x
t = 7 hours
d = ?
Bus two
speed = x + 11
time = 7 hours
d1 = 1015 miles - d
Equations
d = s * t
Bus 1 + bus 2 = 1015
Solution
x * 7 + (x + 11)*7 = 1015
7x + 7x + 11*7 = 1015
14x + 77 =1015
14x + 77 - 77 = 1015 - 77
14x = 938
14x/14 = 938/14
x = 67 miles / hour
x + 11 = 78 miles / hour

and the answer is C
your welcome hope it helps
(x^2 - 3x + 1) - (x^2 + 2x + 7)
Distribute the negative
x^2 - 3x + 1 - x^2 - 2x - 7
Combine like terms
-5x - 6
