Domain: geography (Route Planning and Navigation)
Problem: I plan to travel along the route by combining driving and cycling (starting from Lagos, passing through points A–F in sequence, and finally arriving at Miradouro da Graça in Lisbon). Two of us will be in the car, with bicycles loaded inside. I plan to cycle the relevant segments when the temperature is above 20°C, while my friend follows by car (local temperatures are determined by the nearest city along the route).
I will depart at 12:00 noon on November 1, 2025, and will only move between 9:00 and 17:00 each day, remaining stationary and resting for the rest of the time. Assuming a cycling speed of 27 km/h and a driving speed of 90 km/h, on which day and at what time will we complete the trip?
Answer: Nov.3rd 14:00 (up to 1 hour error)
