Recall your d = rt, distance = rate * time.
let's say the boat has a still water rate of "b", and the current has a a rate of "c", ok.... when the boat is going upstream, is not really going "b" fast, is going slower at "b - c", due to the current going in the opposite direction.
when the boat is coming downstream, is not going "b" fast either, is going faster, is going "b + c", due to the current adding speed to it.
we know the trip up was 108 kms, thus the return trip is also 108 kms.

and surely you know how much that is.
what's the boat's speed? well, 36 + c = b.
Answer:
Can you show the math equation?
Step-by-step explanation:
Answer:
$4.1
Step-by-step explanation:
To find the Unit Rate, you have to find how much it cost of 1 lb. So, you have to divide 16 and 3.99
16/3.99
= 4.01002506
≈ $4.1
Answer:19.1
Step-by-step explanation: Put the numbers in order and then add the numbers and then divide it by how many number there is
14+15+18+18+18+18+21+21+24+24=191
191/10=19.1
