Denise conducted an investigation on the effect of friction on a toy car. Tennis had a ramp that he moved onto four different surfaces. During each trial, he rolled the toy car down the ramp and measured the distance the car traveled from the bottom of the ramp. He repeated the investigation three times on each surface. His data is shown in the table.

Surface Distance (cm) Trial 1 Trial 2 Trial 3

Wood 18 20 18Black Top 16 15 15Gravel 10 10 8Sand 8 7 6

Based on Denise’s results, what should he concludea)The toy car rolled the greatest distance on the woodb)The toy car rolled the shortest distance on the gravel c)The toy car rolled farther on sand than on black top. d)The toy car rolled farther on gravel than on blacktop.
