Jessica runs 8 2/3 miles in 4/3 of an hour. What is her speed? (rate)

6.5miles per hour ~ 6½ miles per hour

Step-by-step explanation:

First convert the distance Jessica ran from a mixed number to a improper fraction:

8⅔ equals 26/3.

Since this a unit rate problem divide the miles by the time traveled.

26/3 (miles) : ¾ (hour). When you divide a number by a fraction use (Keep-Change-Flip).

26/3 * 4/3 = 26/4 miles/hour.

Convert improper fraction to mixed number by dividing 26 by 4.

= 6.5miles / hour. or 6½miles/hour
