Rate x time = distance
b = rate boat travels in still water
c = rate of the current
(b-c)4 = 216
(b+c)4 = 304

4b - 4c = 216
4b + 4c = 304
___________
8b = 520
b = 65 Km/hr

4c = 304 - 4b = 304 - 260 = 44
c = 11 Km/hr

How do i solve this
MAXImum [283]

Answer:

x = 0, x = 3

Step-by-step explanation:

Given

- 4x² = - 12x ( add 12x to both sides )

- 4x² + 12x = 0 ← factor out - 4x from each term

- 4x(x - 3) = 0

Equate each factor to zero and solve for x

- 4x = 0 ⇒ x = 0

x - 3 = 0 ⇒ x = 3
