Distance =9.6 miles
Speed =distance /time
Time=distance/speed=9.6/6=1.6 hours
Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.
Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements
Total permutation (WITH REPERTITION):
7⁷ = 823 543
I don knowwww the association
21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
Answer: 3x^2 + 7x -15
I dunno if u want me to factor it tho
