The given graphs show the progress of two different cyclists during a ride. For each graph, describe the rider’s progress over the period of time
Solution:
(a)The graph of cyclist 1 suggests that as time passes the speed of the cyclist decreases at a constant rate till it becomes zero.
(b) The graph of cyclist 2 suggests that for some time the speed of the cyclist increases at a constant rate and thereafter the speed increases very slowly than before.
✦ Try This: The given graphs show the progress of two different cars during a ride. For each graph, describe the rider’s progress over the period of time.
(A) The graph of car 1 reveals that speed increases for a given time interval followed by a period of constant speed. Later the speed increases increases but at a lower rate than it was initially.
(B) The graph of car 2 tells us that the car's speed increases at first for some time and then it falls for a certain time and finally it runs at a constant speed.
