Can someone me with this math problem

28 miles 
 10 mi + 4 9/16 mi + 13 7/6 mi = 28 miles

10 mi + 4 9/16 mi + 9 mi + 5 7/16 mi =29  miles                                           

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
