Answer: The speed of the river's current is
Step-by-step explanation:
Let's begin by explaining that <u>Speed</u> is a relation between an object's traveled distance in a given time :
So, in this situation the man traveled a distance for a time before realizing he lost his hat.
Keeping this information in mind we can calculate the speed of the river's current, since we already have a reference point: the bridge where the hat fell.
Then:
This is the speed of the river's current

He should have applied the exponent -3 to 4 to get
Answer:
15/40 which simplified is 3/8
Step-by-step explanation:
To solve this equation, we first have to turn all mixed numbers into improper fractions so we can add and subtract them
When we do this we get, 35/5 - (11/4 + 31/8)
Since there is a negative (-) sign before the parentheses, we automatically sub in a -1 in there and we distribute
Now we have 35/5 - 11/4 - 31/8
We can’t subtract this directly since they all have different denominators, so we have to change them to a common denominator
The common denominator of 5 4 and 8 is 40 so we multiply both the numerators and denominators by whatever number it is so the denominators are 40
This gets us to 280/40 - 110/40 - 155/40
When we subtract all of this, we get…
15/40 which can be simplified to 3/8
