x/110 = (320-x)/90
<span> Cross multiply</span>
90x = 35200-110x
200x=35200
X = 35200/200 = 176 (distance traveled by train going 110 mph
176/110 = 1.6 hours = 1 hour and 36 minutes
Check: 110*1.6 = 176, 90*1.6 = 144
176+144 = 320
it will take 1.6 hours ( 1 hour 36 minutes) for the trains to meet

Answer:
B. 3.09-3.10-3.2-3.5 is the answer
To
get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do
this, we will get 20.70, which means that 20.70 milliliters of alcohol were
used. On the other hand, we can get the milliliters of water used through two
ways: the first one is by simply subtracting 20.70 from 690, which will give us
the answer 669.30. Another would be by multiplying 690 by 0.97, which will also
yield the answer 669.30. The number of milliliters of water used was 669.30.
