Answer:
2.3=v+0.47v=
We move all terms to the left:
2.3-(v+0.47v)=0
We add all the numbers together, and all the variables
-(+1.47v)+2.3=0
We get rid of parentheses
-1.47v+2.3=0
We move all terms containing v to the left, all other terms to the right
-1.47v=-2.3
v=-2.3/-1.47
v=1+0.83/1.47
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
