Answer:
y = 1/3x + 1
Step-by-step explanation:
Here speed of first train is slower than speed of second train. So if they catch up , the distance traveled will be same since they left the same station at different times.
But the time traveled will be different .
Let us say the two trains meet at time t ,
Distance = speed * time
Distance traveled by first train = 40 t
Since second train is leaving after three hours , so
Distance traveled by second train = 60(t-3)
As discussed earlier, distance traveled will be same, so

distributing 60 over t-3




t=9
So the second train will meet the first at 9 p.m.
Answer:
B
Step-by-step explanation:
I'm not 100% sure what you want me to do with this but i hope this helps:
x < -3
or if you want me to flip the sign then the solution becomes
x > -3
