Question

Pls help, Jessie had 30 minutes to do a three-problem quiz. She spent 8 7/10 minutes on question A, and 4 2/5 minutes on question B. How much time did she have left for question C? (An thank you for helping!)

Answer 1

16 9/10 minutes

Explanation:

She is solving 3 questions, so her total time spent =

Total time = Time spent on A + Time spent on B + Time spent on C

30 minutes = 8 7/10 + 4 2/5 + Time C

Time C = 30 minutes - (8 7/10 + 4 2/5)minutes

Time C = 30 minutes - (13 1/0 minutes)

Time C = 16 9/10 minutes

Hence, she would have 16 9/10 minutes for question c
