If they are both traveling with the same speed that means that they will reach other in the middle of the line initially between them. In other word, each will have to travel the same amount before they reach other.
Now you can calculate the time it takes for only one locomotive to travel half of the total distance between them, and that time is equal to the time you are looking for.
Use
t = S1/2 / v
where t-time, S-distance traveled , v-velocity

Inertia is the tendency of an object to resist a change in its motion.
Answer:
D) Points down
Explanation:
We can find the direction of the magnetic field produced by each of the wire by using the right hand rule:
- the thumb must correspond to the direction of the current in the wire
- the other fingers wrap around the thumb and gives the direction of the magnetic field lines
For the wire on the right, we have:
- thumb (current): towards you
- other fingers (magnetic field): at the left of the wire, they point down
For the wire on the left, we have:
- thumb (current): away from you
- other fingers (magnetic field): at the right of the wire, they point down
So, both magnetic fields point down at the point halfway between the two wires, so the net field is also pointing down.
