Answer:
8mph
Step-by-step explanation:
Let call X is trip there speed
R x t = D
# to X 3 = 3X
# Return 6 4 = 24
Because the distance when we go to and back are the same, so we have:
3X = 24
<=> X = 8
So the avergage speed of the trip there is 8mph

Answer:
Tn = 2/3^(n-1)
Step-by-step explanation:
The nth term of a geometric progression is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is t common ratio
From the sequence
a = 2/9
r = (2/3)/(2/9) = 2/(2/3) =3
Substitute
Tn = 2/9(3)^(n-1)
Tn = 2/3^(n-1)
Hence the required equation is Tn = 2/3^(n-1)
