Deutsch 30 24 18 12 2. 4 10 Time (s) The graph above shows the speed of a truck as it moves along a straight, level road. Which of the following describe a method to determine the distance d the truck travels during the 10 s time interval shown? Select two answers Mutiply the average speed of 18 m/s by the 10s travel time. Mutply half the inital speed of 30 m/s by the 10 s travel time. Calculane the slope of the line in the graph to determine the acceleration a and then use d- (1/2)at, where tis the travel time Calculate the area under the line in the graph O A B D. 7 9. 10 11 12 13 14 15 16 Next US (su) paod
