Answer :
Initially, it lets off 15 people but picks up 9, for a total change of losing 6 people. If it lets off 4 more people, it has then lost 10 people total.
Answer:
The original number of passengers on the bus decreased by 10 after the second stop
Explanation:
Assume that the total passengers on the bus before 2:30 was x
Now, at 2:30:
15 passengers got off and 9 got on.
This means that:
number of passengers = x - 15 + 9
number of passengers = x -6
10 minutes later:
4 passengers got off the bus
This means that:
number of passengers = (x-6) - 4
number of passengers = x - 10
By comparing, we can note that:
The original number of passengers on the bus decreased by 10 after the second stop
