Step-by-step explanation:
14 kilometers x 4 kilo/minute = 56 minutes
Answer:
The length is 90.033 and the angle that v makes with the positive x-axis is 153.339°
Step-by-step explanation:
Firstly we will have to convert our given vectors to their rectangular Cartesian vector form as follow,

Now that we have these, we can add them to obtain v as follows,

Now that we have the Cartesian vector form we can calculate its length and its direction with respect to the positive x-axis as follows(In fact we usually refer the angles from the positive x-axis),
So the length of the vector is 90.033 and the angle it makes with the positive x-axis is 153.339°.
No image shown but just remember that percentage is out of 100
0.03 is 3%
