Answer:
(B) x + 4y = 7
Step-by-step explanation:
The time when the two trains reach each other is 1.25 hours
The trains are 68.75 away from the city when they reach each other.
(18 + 12q) = 6(2q - 7) Use the Distributive Property on both sides
6 + 4q = 12q - 42 Subtract 12q from both sides
6 - 8q = -42 Subtract 6 from both sides
-8q = -48 Divide both sides by -8
q = 6
