Answer:
20 mph and 4 mph
Step-by-step explanation:
GIVEN: A boat travels upstream for 
miles in 
hours and returns in 
hours traveling downstream in a river.
TO FIND: What is the rate of the boat in still water and the rate of the current.
SOLUTION:
Let the speed of boat in still water be 
and speed of current be 
.
speed of water in upstream 
speed of water in downstream 
As 
Solving both we get
Hence speed of boat in still water and rate of current is 20mph and 4mph respectively.

Answer:
x = 32 words
Step-by-step explanation:
Okay...let's get solving! :D Firstly, we
let the word list be x and convert the long paragraph into an equation that we can use.
one-fourth = 1/4
Memroized = 8 words
Thus, we solve the equation.
x = 32 words
Answer:
Step-by-step explanation:
Yes they would.
2x+3x+x+90=360
6x=270
x=45
Angle A=2x
Angle A=2(45)=90 degrees
So both AD and BC are vertical lines which are parallel to each other.
