It is correct im sure of it
The answer is:
2((4^2)^-1)
= 2 * 16^-1
= 2 * 1/16
= 2/16
Answer = 1/8 (Decimal is 0.125)
“Nerves that extend throughout the body on both sides emerging directly from brain and brain stem are called cranial nerves.”
Let
x = velocity of the water current
t1 = time taken to go downstream
t2 = time taken to go upstream
t1 + t2 = 8
t2 = 8 – t1
v = D/t
Downstream
(4 + x) = 6/ t1
t1 = 6/(4+x)
Upstream
(4 – x) = 6/t2
Substitute expression for t2 to obtain
(4 – x) = 6/ (8-t1)
Substituting the expression of t1 to make a single variable equation, obtaining
6 = (4-x)*(8 – 6/(4+x))
Solving for x,
x= 3.16 m/s
8 times ( 5 times 2+3) = 8 times (15+3) = 8 times 13 + 104
