Answer:
The speed of the boat in still water is 18 mph.
The speed of the current is 2 mph
Step-by-step explanation:
Let x represent the speed of the boat in still water.
Let y represent the speed of the current.
When the boat goes against the current, the speed is 16 mph. Assuming it traveled against the current while going upstream, its total speed would be (x - y) mph. It means that
x - y = 16 (equation 1)
Going downstream, the boat averages 20 mph. Assuming it traveled with the current, its total speed would be (x + y) mph. It means that
x + y = 20 (equation 2)
Adding both equations, it becomes
2x = 36
x = 36/2
x = 18 mph
Substituting x = 18 into equation 1, it becomes
18 - y = 16
y = 18 - 16
y = 2 mph
Answer:
1
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (5-8)/(-8 - -5)
= -3/(-8+5)
= -3/-3
= 1
Answer:
The solution is obtained by dividing the number of flowers by the number of vases.
Step-by-step explanation:
The story problem is very straightforward. Normally, you need to read the problem and understand it.
Let's look at the question again.
Although we do not have all the quantities, we can still show how to solve the problem.
Let x be the total number of flowers.
There are 4 vases.
Therefore, the number of flowers in each vase will be:
x/4
Flow the same rule for similar problems.
