Answer: The average speed of the rollercoaster is 30 meters per second.
Step-by-step explanation:
Hi, since:
Speed rate = distance /time
To answer this question we simply have to divide the length (distance) of the rollercoaster (3,000 meters) by the time spent on traveling it (100 seconds)
Mathematically speaking;
3000 meters / 100 seconds = 30 meters per second
The average speed of the rollercoaster is 30 meters per second.
The answer would be 105.41 Explantaion: 122 • 0.2=24.4 122-24.4=97.6 97.6•0.08=7.808 which rounded to the nearest hundredths would be 7.81 then 97.6+7.81=105.41
