Emily had 20 minutes to do a three-problem quiz. She spent 11 3/4 minutes on question A and 5 1/2 minutes on question B. How much time did she have left for question C?

Correct answer:

C =  2 34 = 11/4 min

Step-by-step explanation:

t=20 min A=1143=11+43=411 4+3=447=11.75 min B=521=5+21=25 2+1=211=5.5 min  s=A+B=11.75+5.5=469=17.25 min  C=ts=2017.25=411 min=243 min=2.75 min
