Answer:
10 minutes maximum
Step-by-step explanation:
well, based on the condition/fact that the bus takes and average of 10 minutes to arrive at a bus stop, you can assume that the previous bus just left(that is worst case scenario), so might have to weight for 1o minutes to get a bus.
Hence for the worst case it is expected that you would have to wait for 10 minutes maximum for the next bus to arrive, or you might even wait for a shorter time.
