Exercise 1 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. 360milesin 6hours Let's write this rate as a fraction. 360miles/6hours To find the unit rate, we need to write an equivalent rate with a denominator of 1 hour. Let's ignore the units for simplicity.

360/6

60/1

Finally, we got the unit rate. 360miles/6hours = 60miles/1hour The unit rate is 60 miles per hour.
