Answer: No

Step-by-step explanation: 1 1/2 divided by 1/6 = 9. Since he said he could mow 1/6 acre in 8 minutes, and he needed to mow 9 x 1/6 acre, we need to multiply 8x9 which equals 72. An hour is 60 minutes so he can't mow 1 1/2 acres in an hour.

A truck rental is $30 plus $.30 /mi. Find out how many miles Ken traveled if his bill was $55.20 .
tangare [24]

Hello and Good Morning/Afternoon:

<u>Let's take this problem step-by-step</u>:

<u>Let's consider the information given</u>:

  • rental price: $30 + $0.30/mile
  • total bill for Ken: $55.20

<u>Let's setup an equation for the cost</u>

  • set 'x' as number of miles traveled

             \hookrightarrow Cost = 30 + 0.3x

  • set that equal to the total cost or bill and solve

             30 + 0.3x = 55.2\\0.3x = 25.2\\x=84

Ken must have traveled 84 miles

<u>Answer: 84 miles</u>

<u></u>

Hope that helps!

Two trains are 210 miles apart, and their speeds differ by 17 mph. Find the speed of each train if they are traveling toward eac
Marizza181 [45]
V1 - velocity first train
v2 - velocity second train
v2 > v1

v2 - v1 = 17 mph

We know, that: 
s_1+s_2=210 \ [miles] \\ \\ t_1=t_2=2h

So:

v_1=\dfrac{s_1}{t_1}=\dfrac{s_1}{2} \\ \\ v_2=\dfrac{s_2}{t_2}=\dfrac{s_2}{2} \\ \\ \\ v_1+v_2= \dfrac{s_1}{2}+\dfrac{s_2}{2} \\ \\ v_1+v_2= \dfrac{s_1+s_2}{2} \\ \\  v_1+v_2= \dfrac{210}{2}=105

NOw we've got simple system of equations:

+\begin{cases} v_2-v_1=17 \\ v_2+v_1=105\end{cases} \\ \\ 2v_2=122 \qquad /:2 \\ \\ v_2=61 \qquad [mph] \\ \\ v_2-v_1=17 \\ \\ 61-v_1=17 \\ \\ v_1=44

Velocities of these trains are  61mph  and 44mph
