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
B. The product of two irrational numbers if rational
Example: The square root of 2 times the square root of 3, is the square root of 6, which is still irrational.
Answer:
2nd term is 8.
nth term is 3n + 2.
Step-by-step explanation:
nth term = 5 + 3(n - 1)
= 3n + 2
Answer:
p
Step-by-step explanation:
6 kilometers is the greatest,but arranging from greatest to least: 6km, 60m, 600 cm or 6000mm
60 meters = 60 meters * 1km/1000 meters = 0.06 km600 centimeters = 600 cm * 1m/100cm * 1km/1000m = 0.006 km6000 millimeters = 6000mm * 1m/1000mm * 1km/1000m = 0.006km
