To find the distance \( d \) that the train travels in 2 hours, we can set up an equation based on the information provided.

The total distance traveled by the train is 60 miles. Since the train travels \( d \) miles in 2 hours, let's express the distance traveled in terms of time.

If we let \( t \) be the number of 2-hour intervals in the total travel time, we can say:
- The number of intervals of 2 hours in the journey is \( \frac{t}{2} \).
- Thus, the total distance traveled can be expressed as:

\[
\text{Total distance} = d \cdot \left(\frac{t}{2}\right)
\]

However, the total time taken could also be used to express \( t \) in hours. If the train traveled for a total of \( t \) hours and completed \( d \) miles in every 2-hour segment, we know:

1. The train travels 2 hours for every segment.
2. Therefore, in \( t \) hours, the number of segments is \( \frac{t}{2} \).

Given that the train travels 60 miles in total, we can set up the equation based on the number of intervals:

\[
\frac{d}{2} \cdot \left( \text{number of segments}\right) = 60
\]

But since we want to find \( d \) directly, it is simpler to write:

Assuming the total travel time is \( T \) and \( T = 2k \) where \( k \) is the number of segments the train travels, we have:

\[
d \cdot k = 60
\]

Given the train covers \( d \) miles in 2 hours, we can represent the total distance covered as:
- \( d + d + d + \ldots (k \text{ terms}) = 60 \)

Which simplifies our equation to:

\[
d \cdot k = 60
\]

The simplest version of the equation is based directly without needing to manipulate into hours, just set the total directly:

\[
k \cdot d = 60
\]

This implies \( d = \frac{60}{k} \) for \( k \) as the number of 2-hour intervals within the total traveled time.

While the above breaks down, from the given data without an interval stated, we conclude to simplify needing \( d \) in primary adjustment yielding:

Every \( d = 2 \text{ hours per traverse yielding to the analysis in 2 also taken in group for velocity in motion } \)

Thus giving representation on capturing \( d \) input as per distance travel in segments.

In simplest terms, our direct representation ensuring \( d \) would yield via:

If \( k = 1 \) as segments each distance \( d = 30 \cdot 2 = 60\) gives hence total of intervals yielding simple then:

\[
d \cdot 2 = 60.
\]

Thus, in differential view:

Results via \( d = 60 \)

Answer assuming \( T=2 \) or yield direct in revised of stated to equal capture:
\[
d = 30 \text{ miles in segment per time of two hours, 30 miles each twice summed accumulating at final.}
\]

So, we find \( d = 30 \text{ miles} \).
