set up the triangle with the information given. then just solve for x.
It is 5 since u need to jump 5 times 4,8,12,16,20=5 times 4
So 6+3 is 9 right? So let's just say it's 9:37 with a 45 min ride. 60 minutes are in a hour. 60 - 37 = 23. We have 23 minutes left until 10:00. 45- 23 = 22. Therefore it'd be 10:22 p.m.
