Answer:
ok so what part
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
3(5)+=17 plug 5 in for x then solve hope this helps
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
The answer would be 102 <span>÷ 34 = 3</span>
