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

Answer:
50 times greater
Step-by-step explanation:
If there are two numbers A and B, where A is greater than B,
If we want to find how many times greater A is to B, we simply divide, so that would be
A/B
Now, we have

and

We simply need to divide to find how much greater is the first number than the second number. Remember dividing numbers in scientific notation:

Thus, we have:

So the first number is 50 times greater than the second
