Exercise 3 Page 44

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. 750yardsin 25minutes Let's write this rate as a fraction. 750yards/25minutes To find the unit rate, we need to write an equivalent rate with a denominator of 1 minute. Let's ignore the units for simplicity.

Finally, we got the unit rate. 750yards/25minutes = 30yards/1minute The unit rate is 30 yards per minute.
