Answer:
Inverse variation
Step-by-step explanation:
Given equation is .
Now we need to identify the type of variation represented by .
We know that there are two type of variations direct and inverse.
If y and x are in direct variation then we write equation as .
where k is the constant of variation.
If y and x are in inverse variation then we write equation as .
Given equation looks similar to
.
So that means finala answer is "Inverse variation".
Speed is the rate of change of distance with time
- The time taken for the entire hike is 5 hours
Reason:
known parameter;
The length of the route = 12-mile
Speed in the first 2 hours = 3 mph
Speed in the rest of the hike = 3 mph
Required:
The time taken, or duration of the entire hike
Solution;
- Distance = Velocity × Time
Distance covered in the first 2 hours, d₁ = 2 hours × 3 mph = 6 miles
Distance left to travel at 2 mph, d₂ = D - d₁
∴ d₂ = 12 miles - 6 miles = 6 miles
Distance left to travel at 2 mph, d₂ = 6 miles
Time to travel the remaining 6 miles,
The time taken for the entire hike, t = t₁ + t₂
Where
t₁ = The first 2 hours
t = 2 hours + 3 hours = 5 hours
The time taken for the entire hike, t = <u>5 hours</u>
