Answer:
Time taken by the un powered raft to cover this distance is T = 192.12 hr
Step-by-step explanation:
Let speed of boat = u 
Speed of current = v 
Let distance between A & B = 100 km
Time taken in downstream = 32 hours


u + v = 3.125 ------ (1)
Time taken in upstream = 48 hours


u - v = 2.084 ------- (2)
By solving equation (1) & (2)
u = 2.6045 
v = 0.5205 
Now the time taken by the un powered raft to cover this distance

Because un powered raft travel with the speed of the current.

T = 192.12 hr
Therefore the time taken by the un powered raft to cover this distance is
T = 192.12 hr
Answer:
y=1/2x
Step-by-step explanation:
if a linear equation has a parallel function then it's going to have to be the same slope as the equation. ie
y=2x+3
and
y=2x-2
are paralell
I think the equation is y= 3/5x-1 1/2
Answer:
24v
Step-by-step explanation:
simply multiply perform the distributive property. so multiply 6 and 4 and you should get 24. after just add in the v.
pls mark brainlest
I think this is the correct answer: * Zc x (sigma/sqrt of n)
c= .95 (Zc of 1.96)
0.711*
