Answer:

The difference between the two trains is the direction in which they move.

Explanation:

Velocity incorporates not only speed, but also direction. In this case, both trains move at a constant speed each of 80 km/hr. However, there difference is that one is moving west, while the other is moving east.

They both travel the same speed apart with the same velocity. This does not teach you anything just common sense

Answer:

1,842,000 of net population growth

Explanation:

Since we have 14 births and 8 deaths per 1,000 people, it means that on every 1,000 people we have 6 people more for that year. Considering that the population is 307 million, we need to see how much 1,000's there are in 307 million:

307,000,000 / 1,000 = 307,000

In order to get the total net population growth we need to multiply 307,000 with the growth on every 1,000 people:

307,000 x 6 = 1,842,000

So we get a net population growth of 1,842,000 for that year.
