Answer: 1 13/30 hrs left
Step-by-step explanation:
his class lasts 2 5/6 hrs...and he has already been in there for 1 2/5 hr
so the time he has left can be found by subtracting the time he has been there from the total time of the class
2 5/6 - 1 2/5....
(2 - 1) = 1 : (5/6 - 2/5 = 25/30 - 12/30 = 13/30)
so he has 1 13/30 hrs left
