I would say the answer is B, it's just what I'm thinking
Answer:
Length 3 cm.
Width 3 cm.
height 9. cm
Step-by-step explanation:
The volume is the length * width * height = LWH.
81 = 3* 3 * 9 so L could be 3, W could be 3 and H could b 9 cm.
Solve for the two velocities:
with the current = 48/6 = 8 mph
against the current = 48/8 = 6 mph
bv= boat velocity in still water
cv = current velocity
A) bv -cv = 6mph
B) bv + cv = 8mph
Adding both equations
2 * bv = 14 mph
boat velocity = 7 mph
current velocity = 1 mph
