<u><em>Answer:</em></u>
The original number of passengers on the bus decreased by 10 after the second stop
<u><em>Explanation:</em></u>
Assume that the total passengers on the bus before 2:30 was x
<u>Now, at 2:30:</u>
15 passengers got off and 9 got on.
<u>This means that:</u>
number of passengers = x - 15 + 9
number of passengers = x -6
<u>10 minutes later:</u>
4 passengers got off the bus
<u>This means that:</u>
number of passengers = (x-6) - 4
number of passengers = x - 10
<u>By comparing, we can note that:</u>
The original number of passengers on the bus decreased by 10 after the second stop

Answer:
Mass of 1 bacterium =2×10-¹²
Therefore, Mass of 480,000,000 bacteria =2×10-¹²×480,000,000
=0.00096
=9.6×10-4
