Answer:
Correct answer: V₁ boat = 16 km/h and V₂ current = 4 km/h
Step-by-step explanation:
If we take speed (velocity) of the boat as V₁ and speed of the current V₂
Let us form equations:
Traveling down the current V₁ + V₂ = 60/3 = 20 km/h
Traveling against the current V₁ - V₂ = 60/5 = 12 km/h
V₁ - V₂ = 12
V₁ + V₂ = 20
If we add up the left and right sides of the equations we get:
2 V₁ = 32 => V₁ = 32/2 = 16 km/h
from the second equation we get:
V₂ = 20 - V₁ = 20 - 16 = 4 km/h
V₂ = 4 km/h

Answer:
The rate of return is 14%
Step-by-step explanation:
The rate of return can be determined by,
RR = 
x 100%
where:
RR is the rate of return
is the final amount = $690 - $6 = $684
is the initial amount = $15 x 40 = $ 600
So that,
RR = 
x 100%
= 0.14 x 100%
= 14%
Therefore, the rate of return is 14%.
Answer:
9
Step-by-step explanation:
Well 344 rounded to the nearest hundred is 300 so times 24 its 7,200 add 4 is 7,204 but take away 12 is 7,192 and there's your answer
