The width of the river = 60m and so Zachary will be able to swim the river without getting tired.
<h3>What is Proportion ?</h3>
When two ratios are equal , the ratio are said to be in proportion.
As given in the question ,
the width of the river has to be determined
Looking at the figure , the triangle formed at the side of the river is a right triangle the hypotenuse will be determined from the Pythagoras theorem
20² +24² = y²
y = 21.2 m
As the corresponding sides are proportional
31.2 : z = 20:50
z = 78.1
The value of the width of the river will be determined by the Pythagoras Theorem
78.1² = 50² + x²
x = 60m
the width of the river = 60m
Therefore Zachary will be able to swim the river without getting tired.

Answer:
4 lbs left after 5 days
Step-by-step explanation:
First, you need to step up an equation!
You know that Soomin has a total of 20 pounds and that she's using it, so you are going to use subtraction.
She uses 3 1/5 pounds per day so you write:
20 - 3 1/5x
and you know that she wants to know how much she has left after 5 days so you replace the x with 5:
20 - (3 1/5) * 5
Multiply first:
20 - 16
After Subtracting you get the answer:
4 lbs left
The distance is 21km because it says each square is 1km and if you count along the squares there are 21
Hope this helps—xoxo
