An earthworm crawled 35millimeters directly toward a rock at a constant velocity. It took the earthworm 2.5seconds to crawl that far. What was the earthworm's velocity?
14 millimeters per second
Explanation;
The velocity of an object is the distance it travels divided by the time it takes to travel that distance. In this case, the earthworm crawled 35 millimeters in 2.5 seconds, so its velocity was ( 350/2.5) = 14 millimeters per second.
