420 m of total distance is covered by the skier on travelling from A to D.
Explanation:
As from the picture, it can be seen that first the skier moved from position A to position B. And the distance covered by this movement is 180 m. Then as the skier travels from position B to position C, the distance between these two positions is 140 m from the figure. As distance is a scalar quantity, the direction is not taken into consideration. So only the magnitudes of the distance between those points are added.
Now, the distance between A to B is 180 m and then from B to C is 140 m, atlast from C to D, the distance is given as 100 m.
So, the total distance will be the sum of all the above found distances. Thus, the total distance will be 180+140+100 = 420 m.
As the question is about distance, so no need to write the direction for it.
Thus, the final answer will be 420 m of total distance is covered by the skier on travelling from A to D.
Length
The metric unit used to measure length in International System (SI) is meter and it is represented by letter m.
Length can be measured by a metric scale.
Mass
The metric unit used to measure Mass in International System (SI) is Kilograms and it is represented by letter Kg.
Mass can be measured by an instrument called Balance.
Volume
The metric unit used to measure Volume in International System (SI) is Liter and it is represented by letter l.
Volume can be measured by a container called graduated cylinder.
Temperature
The metric unit used to measure Temperature in International System (SI) is Kelvin and it is represented by letter K.
Temprature is measured by most common divice called thermometer.
They are inversely proportional to each other
An object with high mass accelerating quickly. Assuming the objects have the same volume, the third choice will be the most dense, and therefore will take a longer time and a stronger opposite force to slow it down to a complete stop due to its high acceleration rate, as well.
