Two students had a toy truck that they rolled down a ramp and across a flat floor. They wanted to know if blocks loaded in the back of the truck would affect how far the truck traveled. They placed different numbers of blocks in the back of the truck and rolled it down the ramp. The graph below shows their results. Based on the pattern you see in the graph, how far do you think the truck will travel with a 3-block load?

• 20 cm

• 40 cm

• 60 cm
