A) 1 hour 40 minutes
B) 3 hours 40 minutes
C) 3 hours 20 minutes
D) 1 hour 50 minutes
Correct Answer: D
Solution :
Total time spent on two days for homework = 3 hours 40 minutes The same amount of time is spent on each of the 2 days. \[\therefore \] Time spent per day on homework \[=\text{3 hours 40 minutes}\div 2=\frac{(3\times 60+40)}{2}\] \[\therefore \] 110 minutes = (60 + 50) minutes = 1 hour 50 minutes.
