The time taken by the boat to travel 32 miles downstream is 2.1 hours and for upstream 3.56 hours.
<h3>What is speed?</h3>
Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
Given that:-
- A paddleboat moves at a rate of 12 mph in still water. If the rover’s current moves at a rate of 3 mph.
- how long will it take the boat to travel 36 miles downstream and 36 miles upstream?
The time taken by the boat upstream will be calculated as:-
( B + W ) Td = D
( 12 + 3 ) Td = 32
( 15 ) Td = 32
Td = 32 / 15 = 2.1 hours
The time taken by the boat downstream will be calculated as:-
( B - W ) Tu = D
( 12 - 3 ) Tu = 32
9 Tu = 32
Tu = 32 / 9 = 3.56 hours.
Therefore the time taken by the boat to travel 32 miles downstream is 2.1 hours and for upstream 3.56 hours.

P is True (x+x does indeed = 2x)
q is False ((3x)(-2y)=-6xy)
pVq is True (TvF is True)
p->q is False (p->q) equiv ~(p^~q) equiv ~(T^~F) equiv ~(T^T) = F
p^~q is True ((T^~F) = T^T = T)
p->~q is True (T->~F)
Answer:
a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.
b. ∅ = 
(Rx/Ry)
Step-by-step explanation:
Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.
The direction of the angle is found as
tan∅ = Rx/Ry
∅ = (Rx/Ry)
That is not correct, it depends on the numbers you are referring to. For instance, 75% of 100 is 75, but 50% of 1000 is 500, so in this case the 50% of a number is higher than 75% of another number. Although, is true that 75% is higher than 50% of the same number always.
