Answer:
<em>Both trains will meet at 2.2 hours (2 hours and 12 minutes).</em>
Step-by-step explanation:
<u>Relative Speed</u>
If two moving objects are traveling through the same line and have speeds v1 and v2 respectively, their relative speed is vr = v1-v2.
Both trains travel toward each other, which means their speeds are of opposite signs.
Let's assume the first train has a positive speed of 65 mph, and the second train has a negative speed of -85 mph. Then, the relative speed is vr = 65 + 85 = 150 mph.
To calculate the time they take to meet, we apply the formula:


Both trains will meet at 2.2 hours (2 hours and 12 minutes).

The answer is C
Step-by-step explanation:
(5/6)(5/8) = 25/48

Hello!!! Princess Sakura here ^^
Step-by-step explanation:
It is
because you should use
then just plug it in using
(1, 4) and (-2, -2).

That eliminates everything except the second one and the third.
So now we would find the b in the equation 

and that's all
