Answer (2)
Convert 2.85 meters to kilometers: 2.85 ÷ 1000 = 0.00285 km .
Convert 2.85 meters to centimeters: 2.85 × 100 = 285 cm .
Convert 2.85 meters to millimeters: 2.85 × 1000 = 2850 mm .
The distances equal to 2.85 meters are: 0.00285 km, 285 cm, and 2850 mm, so the answer is a, c, i .
Explanation
Understanding the Problem We are given a distance of 2.85 meters and asked to identify which of the provided options represent the same distance in different units (kilometers, centimeters, and millimeters). To solve this, we need to convert 2.85 meters into each of these units and then check which options match our converted values.
Converting to Kilometers First, let's convert 2.85 meters to kilometers. Since 1 kilometer is equal to 1000 meters, we divide 2.85 by 1000: 2.85 meters = 1000 2.85 kilometers = 0.00285 kilometers So, 2.85 meters is equal to 0.00285 kilometers.
Converting to Centimeters Next, let's convert 2.85 meters to centimeters. Since 1 meter is equal to 100 centimeters, we multiply 2.85 by 100: 2.85 meters = 2.85 × 100 centimeters = 285 centimeters So, 2.85 meters is equal to 285 centimeters.
Converting to Millimeters Now, let's convert 2.85 meters to millimeters. Since 1 meter is equal to 1000 millimeters, we multiply 2.85 by 1000: 2.85 meters = 2.85 × 1000 millimeters = 2850 millimeters So, 2.85 meters is equal to 2850 millimeters.
Identifying Correct Options Finally, we compare our converted values to the given options: a. 0.00285 km (matches our kilometer conversion) b. 28.5 km c. 285 cm (matches our centimeter conversion) d. 0.285 km e. 2850 cm f. 285 mm g. 0.285 cm h. 28500mm i. 2850 mm (matches our millimeter conversion)
Therefore, the distances that are equal to 2.85 meters are 0.00285 km, 285 cm, and 2850 mm.
Examples
Imagine you're building a small robot that needs to navigate a room. Knowing how to convert between meters, centimeters, and millimeters is crucial for programming its movements accurately. If your robot needs to travel 2.85 meters, you can use these conversions to tell it to move 285 centimeters or 2850 millimeters. This ensures your robot reaches its destination precisely, whether it's avoiding obstacles or following a specific path. Understanding unit conversions is fundamental in robotics and many other engineering applications.
The distances equal to 2.85 meters are 0.00285 kilometers, 285 centimeters, and 2850 millimeters. Therefore, the answers are options a, c, and i . These conversions help us understand how distances relate to each other in different units.
