Exercise 3 Page 13

A rate is a special type of ratio that compares quantities with different kinds of units. A unit rate is a rate that has been reduced to have a denominator of 1 unit. We are given the following rate. 45.5metersin 13seconds Let's write this rate as a fraction. 45.5meters/13seconds To find the unit rate, we need to write an equivalent rate with a denominator of 1 second. Let's ignore the units for simplicity.
