If it takes a bicyclist 25 seconds to reach a speed of 10 km/h from rest, what is her acceleration? For the next 10 minutes, she moves at the constant speed of 10 km/h, and at this time, she applies her brakes, and the bicycle decelerates to a full stop in 5 seconds. What is the total distance travelled by the bicyclist? Determine the average speed of the cyclist during the first 25 seconds, 620 seconds, and 625 seconds.
