A is the answer babygirl.
Answer:
The eastbound train travels at 92 mph and the westbound train travels at 96 mph.
Step-by-step explanation:
We know that Velocity = distance / time
If the eastbound train travels at x miles per hour, the westbound train travels at x + 4 mph.
After 3.5 hours, they are 658 miles apart. If we solve for distance the formula given above we have: Distance = velocity x time. We have that the total distance between both trains is 658 miles.
Substituting the values of the problem and solving for x we have

Thus, the eastbound train travels at 92 mph and the westbound train travels at 96 mph.
Answer:
1. at 1 hour, 3 miles is the distance.
2. at 0 hours, 0 miles is the distance.
3. at 3 hours, 9 miles is the distance.
The terms of an arithmetic progression, can form consecutive terms of a geometric progression.
- The common ratio is:

- The general term of the GP is:

The nth term of an AP is:

So, the <em>2nd, 6th and 8th terms </em>of the AP are:



The <em>first, second and third terms </em>of the GP would be:



The common ratio (r) is calculated as:

This gives

The nth term of a GP is calculated using:

So, we have:
