12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking.
SO here are the data that we need:
=> 8 and ½ miles = 8.5 miles
=> ½ hour = .5 hours or 30 minutes
Now, let’s solve for the unit rate
=> SO in every 30 minutes he bikes around 8.5 miles
=> Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2
=> 8.5 * 2 = 17miles
=> 17 miles / hour
