First find the additional distance between the second store and the third store: 6 miles * 2/3 = <<6*2/3=4>>4 miles
Then add that to the distance between the first two stores to find the total distance between the second and third stores: 4 miles + 6 miles = <<4+6=10>>10 miles
Then add the distance between the first two stores, the distance from Jason's house to the first store, and the distance from the last store to work: 10 miles + 6 miles + 4 miles + 4 miles = <<10+6+4+4=24>>24 miles
