Answer:
1/2 mph
Step-by-step explanation:
Given :
Distance traveled, D = 12 miles
Upstream Swim time = 4 hours
Return swim time = 3 hours
Upstream rate = 12/4 = 3 mph
Return rate = 12/3 = 4 mph
Let
swim rate = s
Current rate = c
s - c = upstream rate
s + c = return rate
s - c = 3 - - - (1)
s + c = 4 - - -(2)
From (1)
s = 3 + c
Put into (2)
3 + c + c = 4
3 + 2c = 4
2c = 4 - 3
2c = 1
c = 1/2 mph
Hence, rate of current = 0.5mph
Answer:
answer is A fosha
Step-by-step explanation:
The same input is being mapped into two outputs, so this is not a function.
<h3>
Does the table represent a function?</h3>
A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.
Here we have the table:
x y
4 2
3 3
4 5
5 6
7 7
As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.
Then this table does not represent a function.
