Answer:
Mai is moving faster than Priya.
Step-by-step explanation:
It is given that Mai traveled 15 meters in 6 seconds.
The speed Mai is
Priya travels 22 meters in 10 seconds. Speed of Priya is
Since speed of Mai is more than the speed of Priya, therefore Mai is moving faster than Priya.
However the 
are chosen, the sum is equivalent to the definite integral,
which can be computed via integration by parts. If
