The ship sails at 20 km / h.
So
20 km / h x 2 h = 40 km
The boat moves 40 km to the northeast.
Then, in the same way:
20 km / h x 1 h = 20 km.
The ship moves 20 km northwest.
We solve this problem using vectors. In this case, we must perform the sum of two vectors a and b
a) magnitude = 40 km and direction 20 degrees east
b) magnitude = 20 km and direction 10 degrees northwest
In Cartesian coordinates, these vectors are written as:
a) 40sin (20º) i + 40cos (20º) j = 13,68i + 37,59j
b) -20sin (10th) i + 20cos (10th) j = -3,473i + 19,70j
The displacement vector of the ship would be the sum of a + b
a + b = 10,207i + 57,29j Finally, the magnitude of the a + b vector will tell us how far the ship is
√(10.21² + 57.29²) = 58.92km
The Answer is : 
Step-by-step explanation:
The data value 2.5 will lie below the second quartile
When adding or subtracting fractions, there is one big rule: make sure the denominators are the same first!
As long as the denominators (the numbers on the bottom of the fraction) are the same, you can get an answer by adding the numerators (the numbers on top) and keeping the denominator the same.
********Here's an example********
2/3 + 3/3
First, make sure the denominators are the same. Since the number on the bottom of each fraction is the same, namely 3, we can proceed without worry.
Now add the numerators. The numbers on top are 2 and 3. 2 + 3 = 5.
The final answer is 5/3. We added together the numerators to get the top number, and kept the denominator the same for the bottom number.
***************************************
Try adding 3/4 and 4/4 together on your own now before you look ahead.
To get the answer, let's follow the process.
Make sure the denominators match. They do, so we can proceed.
Add the numerators. 3 + 4 = 7.
Keep the denominator the same. The denominator is 4.
Your answer is 7/4!
