To solve this question, we need to convert the given distance in kilometers (km) to meters (m). For this, we use the relationship between the units of measurement, where 1 km is equal to 1,000 m. Step by step: 1. Identify the distance given in kilometers: 3 km. 2. Convert the distance from kilometers to meters, using the relationship 1 km = 1,000 m. 3. Perform the multiplication: 3 km * 1,000 m/km. Calculation: 3 km * 1,000 m/km = 3,000 m. Therefore, the truck driver will have to travel 3,000 meters to the restaurant indicated on the sign. The correct answer is "3 000", compared to the other alternatives: "300", "30", and "3".
