Match the distance/time graphs to the motion description.

the speed of the car is decreasing.

the car is traveling at a constant speed.

the car is coming back.

the car is stopped.

Graph A represents constant speed so the answer for this is the car is moving at constant speed. Time is increasing to the right, whereas distance is increasing constantly with time. 
Graph B represents the car is coming back because from the starting point it is decreasing because while velocity is +, the magnitude keeps on lowering.
Graph C represents the car is stopped since it time increasing to the right but there is no change in speed.
Graph D represents the speed of the car is decreasing because distance in each time interval is decreasing.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
