Answer: 2mp
Step-by-step explanation: Let "b" represent the speed of the boat in still water
Let "c" represent the speed of the current
Let "t" represent time
Downstream(same direction) =(b+c)*t
Upstream(against current)=(b-c)*t
(b+c)*3=24
(b-c)*4=16
3b+3c=24....all sides can be divided by 3 =b+c=8
4b-4c=16.....all sides can be divided by 4 =b-c=4
Use Elimination method
b+c=8
b-c= 4 Subtracting
=====
2c=4
find c by dividing both sides by 2. c=2
if c=2, substitute to get b
b+2=8
-2=-2
======
b=6
Speed of boat in still water =6mph
rate of current=2mp
Step-by-step explanation:
making x subject in eq 1
x= (-1-9y)/-14
substituting the value of x in eq 2
17(-1-9y/-14)=7+9y
(-17-153y)/-14=7+9y
-17-153y=-98-126y
-17+98=153y-126y
81=27y
y=3
substituting this value of y in eq 1
-14x=-1-9(3)
-14x=-28
x=2
(x,y) = (2,3)
Answer:
The total distance of the rectangular garden is the perimeter of the garden.
Step-by-step explanation:
Since the garden is in a rectangular shape. So, the perimeter of the rectangular garden is the distance on which Mr. Hoges can build the fence. However, the perimeter can be determined by adding all the sides. A rectangular shape contains four sides and opposite sides are equal. Thus, it can be determined by using the below formula;
Where
l = length of the garden
b is the breadth of the garden
That would be 2.1 because if it's in decimal it's 2.1
