A manatee can swim 5 miles in 1 1/4 hour. If the manatee swims at the same average speed, how far can it swim in one hour?
Ah -- now it makes sense.
5/(1 1/4) = x/1
(1 1/4)x = 5
x = 5 / (5/4)
x = 5 * (4/5) = 20/5 = 4 miles
I’m super sorry haha
It's o.k.
Sometimes new technology screws us up more than helps us.
I know a retired professor who is blind. It took him a lot of practice to master the technology to translate voice into written words.
To find out how far the manatee can swim in one hour, we can use a proportion. Let's set up the proportion:
Distance covered / Time taken = Average Speed
Let's assign variables to the given values:
Distance covered = x (unknown)
Time taken = 1 hour
Average speed = 5 miles / (1 1/4 hour)
First, let's convert 1 1/4 hour to an improper fraction:
1 1/4 = (4 * 1 + 1) / 4 = 5/4 hour
Now, we can rewrite the average speed:
Average speed = 5 miles / (5/4 hour)
Next, let's simplify this expression by multiplying the average speed fraction by the reciprocal of the time fraction:
Average speed = 5 miles * (4/5 hour)
Now, multiplying the numbers:
Average speed = 20/5 miles per hour
Average speed = 4 miles per hour
Now that we have the average speed, we can substitute it back into our proportion:
Distance covered / 1 hour = 4 miles/hour
So, the manatee can swim 4 miles in one hour.
