Answer:
Distance between B and C = 
Step-by-step explanation:
Let the time taken to reach from station A to B be x hr
Let the time taken to reach from station B to C be y hr
Given total time from station A to C be 6 hr
∴ x + y = 6
⇒ y = 6 - x → (1)
Also total distance given is 285 miles
As 
∴ distance travelled between station A and B
=
distance travelled between station B and station C
=
So, 40x + 55y = 285
⇒ 40x + 55(6 -x) = 285 (From 1)
=> 40x + 330 - 55x = 285
=> -15x = 285 - 330
=> -15x = -45 ⇒ x=3
gives y = 6-3 = 3 hours
Distance between B and C = 
Answer:
The total number of ways are 30.
Step-by-step explanation:
Consider the provided information.
We need to write 3-letter "words" from the letters of "Adelphi" so that the first and last letters are vowels.
The number of letters in "Adelphi" = 7
The number of vowels are = 3
It is given that the first and last letters are vowels.
For first letter we have 3 choices, and for the last letter we have 2 choices as repetition is not allowed.
If we have selected first and last letter that means now we have 5 letters for the middle letter. (7-2=5)
So the number of possible choices for the 2nd letter is 5.
Hence, the total number of ways are: 3×5×2 = 30 ways
Answer: y= -2/5x + 2
Step-by-step explanation:
Y= Mx + b
M is the slope
B is the y intercept
The y intercept will be out on the y axis
The slope will be rise over run ( do you first then do to the right!)
