Answer:
1 2/9 minutes
Step-by-step explanation:
55 mph
55 / 60 = 11/12
11/12 of a mile = 1 minute
45 mph
45 / 60 = 3/4
3/4 of a mile = 1 minute
11/12 divided by 3/4
11/12 * 4/3
We can cross-cancel
11/3 * 1/3 = 11/9 = 1 2/9
It takes 1 2/9 minutes for the hummingbird to cross the lake

The frequency is how often something occurs. Here 15. It occurred 15 times that the participants scored in the interval given.
The relative frequency (expressed as a percent) looks at how often something occurred relative to the overall occurrences. Here 15/60 = 1/4 = 25%
The relative frequency is 25%
