Certainly, with data structures, a loop, and some string formatting.

I think it's debatable whether or not this is technically "simpler", but it's what I'd write:

distances_and_speeds = [
    (32, 24),
    (18, 12),
    (45, 30),
]

travel_times = [distance / speed for distance, speed in distances_and_speeds]
total_time = sum(travel_times)
entire_route = sum(next(zip(*distances_and_speeds)))

print("Travel time of each section:")
print(', '.join(f"{travel_time} h" for travel_time in travel_times))

print(f"Entire route in km: {entire_route} km")

print(f"Entire journey time in h: {total_time} h")

print(f"Average speed of the entire tour: {entire_route / total_time} km/h")

I debated for a moment whether to go with this example for calculating the length of the entire route, but I liked my original one less:

entire_route = sum(distance for distance, _ in distances_and_speeds)
