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
Hope this helps!

The hummingbird will take 1 minute 13 seconds.
Let the time that will be taken by the hummingbird be represented by x
Note that 1 minute = 60 seconds
Based on the information given, the equation that'll be used in the question will be:
45/55 = 60/x
Cross multiply
(45 × x) = (60 × 55)
45x = 3300
x = 3300/45
x = 73.33 seconds
x = 1 minute 13 seconds
The hummingbird will take 1 minute 13 seconds.
