A school bus decelerates so that each second it travels 5% less than the distance traveled in the previous second. Given that the bus is traveling at 30 meters per second during the first second during the second of deceleration, how far does the bus travel in 5 seconds? Round your answer to the nearest tenth.

Answer 1

Do you recognize any kind of series in this problem? If so, which one?
How far does the bus travel during the first second? What was the initial speed of the bus? What's the speed during the second second? Is speed constant or changing (decreasing)? What is the common ratio? Is there a formula for the sum of the first n terms of this series?

Answer 2

geometric; 30; 30mps; 5% less of 30; changing; 0.95?; don't know
