You are hiking on a trail that leads to the top of a mountain. At 1 P.M. you reach an elevation of 4400 feet. At 4 P.M. you reac

shusha [124]

Let
t = time, hours
h = height, feet

At 1 PM, the time and height are respectively
t₁ = 1 hour
h₁ = 4400 feet

At 4 PM, the time and height are respectively
t₂ = 4 hours
h₂ = 5600 feet

By definition, the mean hourly change in elevation is
$\frac{h_{2} - h_{1}}{t_{2} - t_{1}} = \frac{5600-4400}{4-1} = \frac{1200}{3} =400$

Answer: 400 feet per hour

5) Solve: 2.4p + 6 = 48

KatRina [158]

Answer:

p = 17.5

Step-by-step explanation:

This is the answer because:

1) First, we have to isolate x

2) To isolate x, first -6 from +6 and 48

+6 - 6 = 0

48 - 6 = 42

Equation: 2.4p = 42

3) Now we are left with 2.4p = 42

4) Next, divide 2.4 from 2.4 and 42

2.4/2.4 = 0

42/2.4 = 17.5

5) We are left with

p = 17.5

Therefore, the answer is p = 17.5

Hope this helps!
