Answer:The Average Rate Matt ran = 10 1/2 miles per hour

Explanation:

Matt's average rate, in miles per hour is referred to as Average Speed which is given as

Average Speed =Distance /Time

Distance for the first part of journey = 3 1/2 miles

Time = 1/3 hour

Average Rate ( Speed) = 3 1/2 miles ÷ 1/3

= 7/2 ÷ 1/3

= 7/2 x 3/1

= 21/2 = 10 1/2 miles per hour .
