Based on the data in the table, which hypothesis is most likely tested in this investigation?

• If the surface is rough, then a car will travel faster.

• If the ramp is taller, then the car will travel a shorter distance.

• If the ramp is taller, then the car will travel a greater distance.

• If the car has more mass, it will go further.
