if a marble took 1.63 seconds to go the first 50cm's, and 1.89 seconds to go the second 50cm's, and then 2.69 seconds to go the whole 100cm's, what was the average velocity and acceleration for the marble?

Extra info: The table was tilted 20 degrees upwards


Please answer an real answer and not a bunch of random words or letters, or I will report you. Thank you! <3
