Task 1: Solve a Complex Word Problem

Prompt: A train travels at an average speed of 60 km/h for the first half of its journey and at 90 km/h for the second half. If the total journey takes 5 hours, what is the total distance traveled?

Claude 3.5 Sonnet's Response:

To solve this problem, let's break it down step by step:

Let's denote the total distance as x km.
The journey is divided into two equal halves in terms of distance. So each half is x/2 km.
For the first half:
- Distance = x/2 km
- Speed = 60 km/h
- Time = Distance / Speed = (x/2) / 60 hours
For the second half:
- Distance = x/2 km
- Speed = 90 km/h
- Time = Distance / Speed = (x/2) / 90 hours
We know that the total time is 5 hours. So we can set up an equation:
(x/2) / 60 + (x/2) / 90 = 5
Let's solve this equation:
- (x/2) / 60 + (x/2) / 90 = 5
- (3x/180) + (2x/180) = 5
- 5x/180 = 5
- x = 180

Therefore, the total distance traveled is 180 km.

GPT-4o's Response:

Let's approach this step-by-step:

Let's say the total distance is x km.
The journey is split into two equal parts in terms of distance. So each part is x/2 km.
For the first half:
- Distance = x/2 km
- Speed = 60 km/h
- Time = Distance / Speed = (x/2) / 60 h
For the second half:
- Distance = x/2 km
- Speed = 90 km/h
- Time = Distance / Speed = (x/2) / 90 h
We know the total time is 5 hours. So:
(x/2) / 60 + (x/2) / 90 = 5
Solving the equation:
(x/120) + (x/180) = 5
(3x/360) + (2x/360) = 5
5x/360 = 5
x = 360

Therefore, the total distance traveled is 360 km.

Analysis of Logical and Mathematical Reasoning

Both Claude 3.5 Sonnet and GPT-4o demonstrated strong logical and mathematical reasoning skills in approaching this problem. However, there are some notable differences:
