For a science experiment, Maria threw an egg 88.2 meters in 3 seconds. What was the average rate of speed of the egg? A. 88.2 m/sec. B. 44.1 m/sec. C. 29.4 m/sec. D. 9.8 m/sec.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
