Merry Christmas and a happy new year
Answer:
30 miles
Step-by-step explanation:
We know
D = RT
Where
D is the distance
R is the rate
T is the time
<u>Towards Island:</u>
R = 15
Let time be x
So, we can write:
D = 15x
<u>Return from Island:</u>
R = 10
Let time be y
So, we can write:
D = 10y
Also, total time is 5 hours, so we can write:
x + y = 5 [equation 2]
Now, since the distance for both legs of the journey is equal, we can write:
Distance 1 = Distance 2
15x = 10y
Now we replace this equation with equation 2, so we get:
Equation 2: x + y = 5 or x = 5 - y
15x = 10y
15(5 - y) = 10y
75 - 15y = 10y
75 = 25y
y = 75/25
y = 3
Distance 2 = D = 10y
Replacing y with 3, we get:
D = 10y
D = 10(3)
D = 30
So, the distance to island is 30 miles
Answer:
42
Step-by-step explanation:
28 + 14
yeah-ya...... right?
Looking at the diagram, you can tell that y and 116 degrees are supplementary, meaning that they add up to 180 degrees.
therefor 180-116=y
y =64
if we add all the angles we know together, 64 + 72 + 125 = 261
360 - 261 = 99
therefor x = 99
6 x 10^3
This would be a good enough answer.
