Question 912620: Start from 110 feet away, a person on a bicycle rides toward a checkpoint and then passes it. The rider is traveling at a constant of 30m feet per second. The distance between the bicycle and the checkpoint is given by the equation d=(110-30t). At what times is the bike 40 feet away from the checkpoint? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Convert feet to meters
1 foot = 0.3048 meters
d = 110*0.3048 - 30t
|110*0.3048 - 30t| = 40
Solve for t (2 times, approaching & departing)
