I have a simple Physics question, which (possibly) has a misleading line, which can have multiple interpretations.
A bus goes past a cyclist every 6 minutes.
It's given that they're going in the same direction. Assuming that goes past means something like passes by, I'm considering 2 scenarios here. The speed of Bus can be:
- Higher than the cyclist's.
- Lower than the cyclist's.
Solving both cases gives different results, whereas, the solution that is given in the book only considers case 1. Am I wrong in considering 2 cases? If yes, is there any rule which I'm forgetting? If no, why do you feel the solution written only considered 1 case? Either case, please direct me to a good reference that can explain the exact meaning of the word.
P.S.: I know it's common sense that the average speed of bus would be more than a cyclist in practical situations, but we can't make such assumptions in a theoretical problem in Physics.
In case you feel it's a naive question, please pardon my lack of knowledge, I'm not a native English speaker.
Edit: Adding this to clarify meaning.
It's given that:
- There are multiple buses (with same speeds).
- Everyone (all buses and cyclist) is going in the same direction.
- Everyone has a constant speed.
Edit 2: All the answers that I saw have referred to the general usage of the word, rather than a stricter definition. As I've already mentioned in the question:
Either case, please direct me to a good reference that can explain the exact meaning of the word.
I'm quoting again to emphasize it.
I know how the word is generally used. My 1st intuition after reading that sentence was also to only consider the case where a bus overtakes the cyclist, but on spending some time with the question, I realized the other case. I believe any question like this should be very clear about it's meaning. If there no strict definition of the word, it makes the question language questionable.
I'm not posting any more details of the problem. It's a lengthy Physics problem and posting more details will only complicate it with unnecessary details.
