Question
In a given scale of 5cm = 40m/hr, how long should you draw a velocity vector of 265m/hr?
Group of answer choices:
- 6.625cm
- 33.125cm
- 2,120cm
- 53cm
Solution
To solve this problem, you need to set up a proportion to find the length of the velocity vector.
The given scale is 5cm = 40m/hr.
So, the proportion is 5cm/40m/hr = x cm/265m/hr.
To solve for x, cross multiply:
5cm * 265m/hr = 40m/hr * x cm
1325cm = 40x
Then, divide both sides by 40 to solve for x:
x = 1325cm / 40 = 33.125cm
So, you should draw a velocity vector of 33.125cm to represent a velocity of 265m/hr.
