Mr Morrison and his daughter Rose both have very bad coughs. They go to the pharmacy and they each get a bottle of QwikQure Cough Medicine. Mr Morrison’s bottle has 300ml and he has to take 10ml every 3 hours. On the other hand, Rose is given a smaller bottle with only 90ml and she has to take 5ml every 6 hours. They have to take the medicine between the hours of 7am and 7pm.
