Time P5 2009 SA2 RGS P1 Q26

Ali was given 0.18 litres of cough mixture by the doctor. He had to take 10 ml of it every 4 hours. How many days would he take to finish the cough mixture?


180 / 10 = 18 times

18 - 1 = 17      Exclude the 1st time he took the cough mixture as time is 0 h

17 x 4 = 68 hours

68/24 = 2 5/6 days
