Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 1 - No. 26)
How can you determine the speed of an object at a specific point in time from a speed-time graph?
Find the gradient at that point
Find the area under the curve up to that point
Read the value on the y-axis at that time
Read the value on the x-axis at that time
Vysvětlení
The speed at a specific time is read directly from the y-axis.
