At the beginning of my bike ride I feel good, so I can travel 20 miles per hour. Later, I get tired and travel only 12 miles per
Vesnalui [34]

Answer: 3\dfrac{1}{4} hours

Step-by-step explanation:

Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.

As per given , we have

x+y= 8

Since : Distance = Speed\times Time

So , we have

20x+12y=122

According to the given question , we have the following system of equations ,

x+y= 8--------(1)\\\\20x+12y=122------------------(2)

Multiply 12 on both sides of equation (1) , we get

12x+12y=96------------(3)

Eliminate equation (3) from (2) , we get

8x=26\\\\\Rightarrow\ x=\dfrac{13}{4}=3\dfrac{1}{4}

Hence, you felt 3\dfrac{1}{4} hours good.

Answer:

\Huge\boxed { 1/4}

\Huge\boxed {226•333. miles}

Step-by-step explanation:

\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩1.solusion✩}}}}}}}}}

1. ⟾ one dozen = 12, so 2 dozen = 12×2=24

⟾ 24 Joe's doughnuts = $6

⟾ 1 Joe's doughnuts or unit / rate = $6/24 = $1/4.

⟾ so per doughnut unit rate is $ 1/4.

\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩2.solusion✩}}}}}}}}}

2. ⟾ 24 hours = 5432 miles.

⟾ 1 hours = 5432/24 hours

⟾ 1 hours = 226•333 miles.

⟾ so aryan drove in 226•333 miles in 1 hours.

Hope it's helps you
