    Find how long a marble rolls down a ramp, given distance and angle

    So then since the angle of the ramp is at 6.9° the time it would take the marble to roll down the ramp would take longer than if it were straight up and down.

    Find how long a marble rolls down a ramp, given distance and angle

    I'm not sure if the angle is relevant information for solving the problem or not. But the length of the ramp and the angle its at are the only given data I have. The marble does roll down the ramp.
