A student observes a speed-time graph for a car that moves with constant speed for 10 seconds, then accelerates for 5 seconds. How can the student use the graph to calculate the total distance travelled during these 15 seconds?
By calculating the area under the speed-time graph for each section and adding them
By using only the area under the acceleration section
By reading the final speed at 15 seconds and multiplying by 15
By multiplying the total time by the average speed shown on the graph
By calculating the area under the speed-time graph for each section and adding them
