Problem Analysis

Two tourists want to simultaneously reach a station that is 30 km away from them. The first tourist can walk at a speed of 5 km/h, while the second tourist can ride a bicycle at a speed of 15 km/h. We need to find the shortest time it would take for both tourists to reach the station.

Solution

To find the shortest time, we need to calculate the time it would take for each tourist to reach the station using their respective speeds. The tourist who takes less time will determine the total time it takes for both tourists to reach the station.

Let's calculate the time it would take for each tourist to reach the station:

1. Tourist 1 (Walking): - Speed: 5 km/h - Distance: 30 km - Time = Distance / Speed = 30 km / 5 km/h = 6 hours

2. Tourist 2 (Bicycling): - Speed: 15 km/h - Distance: 30 km - Time = Distance / Speed = 30 km / 15 km/h = 2 hours

Since Tourist 2 takes less time (2 hours) to reach the station compared to Tourist 1 (6 hours), the total time it takes for both tourists to reach the station is 2 hours.

Therefore, the two tourists can reach the station simultaneously in 2 hours.
