Answer:

\bar v = 60\,mph

Step-by-step explanation:

The distance travelled by Lisa in the first four hours of her trip is:

\Delta s = \left(50\,mph)\cdot (4\,h)

\Delta s = 200\,mi

The distance remaining and her average speed are, respectively:

\Delta s_{R} = 440\,mi - 200\,mi

\Delta s_{R} = 240\,mi

\bar v = \frac{240\,mi}{4\,h}

\bar v = 60\,mph

A truck uses 1 gallon of diesel for every 12 miles traveled. The amount of diesel left in the gas tank, r gallons, after traveli
Snezhnost [94]

<em>The question has missing details. However, general questions that could be asked is as follows:</em>

<em>(1) The number of miles traveled after using (say) 5 gallons</em>

<em>(2) The number of gallons used after traveling for (say) 36 miles</em>

Answer:

See Explanation

Step-by-step explanation:

Given

s = 120 - 12r

A linear equation is represented as:

y = c + mx

Where

c =y\ intercept and

m = slope.

c, in this question represents the initial capacity of the tank.

So, the initial capacity is 120 liters

Solving (a): r = 5

s = 120 - 12r

s = 120 - 12 * 5

s = 120 - 60

s = 60

<em>60 miles traveled</em>

Solving (b): s = 36

s = 120 - 12r

36 = 120 - 2r

Collect like terms

2r =120 -36

2r =84

Solve for r

r = 42

<em>42 gallons used</em>
