The correct answer is D. direction.
An odometer is a device that measures the distance traveled by a vehicle. It is typically located on the dashboard of the vehicle and displays the total distance traveled as well as the current mileage. A compass is a device that is used to determine direction. It consists of a magnetized needle that always points north.
The odometer and the compass are both tools that are used to help people navigate. The odometer helps people to track their distance traveled, while the compass helps people to determine their direction. Both tools are essential for safe and efficient travel.
The other options are incorrect because they do not accurately describe the relationship between an odometer and a compass. Option A, speed, is incorrect because an odometer does not measure speed. Option B, hiking, is incorrect because an odometer is not typically used for hiking. Option C, needle, is incorrect because an odometer does not have a needle.
