The displacement is 2 m south
Explanation:
Distance and displacement are two different quantities:
- Distance is the total length of the path covered by an object during its motion, regardless of the direction. It is a scalar quantity
- Displacement is a vector connecting the initial position to the final position of motion of an object. The magnitude of the displacement is the distance in a straight line between the two points
For the car in this problem, the motion is:
10 m south
8 m north
Taking north as positive direction, we can describe the two parts of the motion as
m
Therefore, the final position of the car with respect to the original position is
which means 2 m south: so, the displacement of the car is 2 m south.

The child at 5 years old would weight: 60 lb (27.16 kg) If he continues gaining weight a that rate
To solve this problem we will use a rule of three with the problem information:
3 years-------- 36 lb child's weight
5 years -------- x
Applying the rule of three we get:
x = ( 5 years * 36 lb child's weigh) / 3 years
x = 60 lb
By converting the weight units from lb to kg we have:
x = 60 lb * 16.3 kg/36 lb
x = 27.16 kg
<h3>What is rule of three?</h3>
It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.
