Ok so R=alfonso's rate
w=wind rate=4
d=rt
with wind rate is R+4
agaoins wind rate is R-4
with wind distance is 34
against is 18 miles
time is same
34=(r+4)t
18=(r-4)t
34=(r+4)t
divide both sides by (r+4)
34/(r+4)=t
18=(r-4)t
divide both sides by (r-4)
18/(r-4)=t
18/(r-4)=t
34/(r+4)=t
set equal to each other
18/(r-4)=34/(r+4)
multiply both sides by (r-4)(r+4)
18(r+4)=34(r-4)
distribute
18r+72=34r-136
subtract 18r from both sides
72=16r-136
add 136 to both sides
208=16r
divide both sides by 16
13mph
answer is 13mph with no wind
Hey there! I'm happy to help!
A permutation is focused on a specific order, while a combination is not focused on the order but on the content of what is grouped.
AB and BA are different permutations because they are in different orders, but they are the same combination because they both contain the letters A and B.
So, we see that AB and BA are one combination.
AC and CA are also another combination because they are made up of the letters A and C.
Same goes for BC and CB, this is also one combinations.
This totals up to C. 3 combinations. Now you know the difference between permutations and combinations!
Have a wonderful day!
