You should be able to calculate gradients of velocity-time graphs and the areas under the graphs.
The gradient of a line on a velocity-time graph represents the acceleration of the object. Study this velocity-time graph.
What is the acceleration represented by the sloping line?
The area under the line in a velocity-time graph represents the distance travelled. To find the distance travelled in the graph above, we need to find the area of the light-blue triangle and the dark-blue rectangle.
Watch this illustrated podcast for a summary of distance/time and velocity/time graphs.
