If it takes Alex 20 minutes to walk from home to School and it takes him 10 minutes to walk from home to the supermarket, which of the following COULD be true?
I. The School is closer to Alex's home than the supermarket.
II. To walk to School, Alex will spend double the time it takes him to walk to the supermarket.
III. Alex will spend more time walking to the school than walking to the supermarket.
Select the correct option:
A) I only
B) I and II only
C) I and III only
D) II and III only
E) I, II and III
Let’s check each statement.   Statement I:The School is closer to Alex's home than the supermarket. Alex spends 10 minutes to walk to the supermarket and spends 20 minutes to walk to school, it takes him longer time to get to school in which case Statement I can NEVER be true.   Statement II: To walk to School, Alex will spend double the time it takes him to walk to the supermarket. Alex spends 10 minutes to walk to school, double that time is 20 minutes. The time taken to walk to school is actually double the time taken to walk to the supermarket in which case Statement II is TRUE.   Statement III: Alex will spend more time walking to the school than walking to the supermarket. Alex spends 20 minutes walking to school and spends 10 minutes walking to the supermarket. Obviously more time is taken to walk to school than walking to the supermarket, in which case Statement III is TRUE.   Statement II and III are true.   So,the correct answer is II and III only.
