A282 kg bumper car moving 3.50 m/s collides with a 155 kg bumper car moving -1.38 m/s. afterwards the 282 kg car moves at 1.10 m/s. find the velocity of the 155 kg car afterwards?

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.
