We don't know her average speed, because insufficient information is provided. We can say it is less than 70 mph and greater than 0 mph.

Jill's average velocity is zero, because her net travel distance is zero.

Her average velocity is 0 as the displacement is zero. Her average speed can be found out if we know the circumference of the roller coaster and if we also know the total time taken.
