Answer:
The area of the speed-time graph gives us the distance travelled . In this case we drop a perpendicular from v=4 to t=2 . Hence, we get a rectangle and a triangle. Now we calculate the areas of the rectangle and the triangle. Rectangle = 2×4=8 m and triangle =1/2×(4–2)×4=4 m. Now to get the distance travelled we add the two up. Hence, distance travelled= (8+4)m =12 m.
This is quite easy, but anyway:
In order, they are
3, 4, 4, 5, 5, 5, 5, 7, 7
7 - 3 = 4
4 would be the range
Answer:

Answer:
3/10
Step-by-step explanation:
