You are driving home on a weekend from school at 55 mi/h for 110 miles. it then starts to snow and you slow to 35 mi/h. you arri
stepladder [879]

Okay lets get started.

I drove 110 miles with speed of 55 mi/hr so the time taken =

time = distance / speed

time = 110 / 55 = 2 hrs For the distance which is covered with 55 mi/hr speed.

Total time for reaching home is 4 hrs 15 minutes. (given in question)

Means rest distance after snow is covered in = 4 hrs 15 minutes - 2 hrs

= 2 hrs 15 minutes = 2 + 15/60 = 2.25 hrs

The speed in snow driving is 35 mi/hr

So distance covered in snow driving is = 2.25 * 35 = 78.75 miles

Hence the total distance = 110 + 78.75 = 188.75 miles : Answer

Hope that will help :)

C

Step-by-step explanation:

10^5=100,000

100,000*4.7=470,000  (Four Hundred Seventy Thousand)

10^8=100000000

100000000*3.9=390,000,000 (Three Hundred Ninty Million)

10^5=100,000

100,000*5.2=520,000 (Five Hundred Two Thousand)

The line y =3x-5 meet x-axis at the point M. The line 3y+2x=2 meets y-axis at point N. Find the equation of the line joining M a
Law Incorporation [45]

<u>Answer-</u>

<em>The line equation is,</em>

\boxed{\boxed{6x+15y-10=0}}

<u>Solution-</u>

The line y =3x-5 meets x-axis at the point M, i.e M is the x-intercept of this line. At the x-intercept y=0, so

\Rightarrow 0 =3x-5

\Rightarrow 3x=5

\Rightarrow x=\dfrac{5}{3}

So, coordinate of M is (\dfrac{5}{3},\ 0)

The line 3y+2x=2 meets y-axis at point N, i.e N is the y-intercept of this line. At the y-intercept x=0, so

\Rightarrow 3y+2(0)=2

\Rightarrow 3y=2

\Rightarrow y=\dfrac{2}{3}

So, coordinate of N is (0,\ \dfrac{2}{3})

The line joining M and N can be found out by applying two point formula of straight line,

\Rightarrow \dfrac{y-y_1}{y_2-y_1}=\dfrac{x-x_1}{x_2-x_1}

\Rightarrow \dfrac{y-0}{\frac{2}{3}-0}=\dfrac{x-\frac{5}{3}}{0-\frac{5}{3}}

\Rightarrow \dfrac{y}{\frac{2}{3}}=\dfrac{x-\frac{5}{3}}{-\frac{5}{3}}

\Rightarrow -\dfrac{5}{3}y=\dfrac{2}{3}(x-\frac{5}{3})

\Rightarrow -5y=2(x-\dfrac{5}{3})

\Rightarrow -5y=2x-\dfrac{10}{3}

\Rightarrow 2x+5y-\dfrac{10}{3}=0

As it is given that all the coefficients are integers, so multiplying with 3

\Rightarrow 6x+15y-10=0
