Question

A ball was bounced 3 times between 3:15p and 3:18p, thrown 10 times between 3:20p and 3:30p and bounced 7 times between 4:15p and 4:20p. What is the rate per hour of ball bouncing based on a 2 hour data collection time period.

Answer 1

strange phrasing of a question

If one assumes that the "observation" was from 3:00 pm - 5:00 pm (2 hours)
