Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 65 kilometers per hour. The eastbound train travels at 85 kilometers per hour. How long will it take for the two trains to be 330 kilometers apart? Do not do any rounding.

Answer:

2.098 hours

Step-by-step explanation:

∫65x + ∫85x = 330

[tex]\frac{65}{2} x^2[/tex] + [tex]\frac{85}{2} x^2[/tex] = 330

[tex]x^2 = \frac{330}{75}[/tex]

[tex]x^2 = 4.4\\x = 2.098[/tex]
