WebMay 25, 2024 · Chemists need to be concerned with the rates at which chemical reactions occur. Rate is another word for speed. If a sprinter takes 11.0 seconds ( s) to run a 100 meter (\left ( m \right)\) dash, his rate or speed is given by the distance traveled divided by the time (see figure below). (8.1.1) speed = distance time = 100 m 11.0 s = 9.09 m/s. WebEnter your login details to start using our mobile-friendly educational games, simulations and puzzles.
