A plane flew 525 miles in 1.75 hours. Find the average speed of the plane.
ale4655 [162]

We are trying to find the average speed of the plane, which is mph, or \dfrac{\textrm{miles}}{\textrm{hour}}. Using proportions, we can find the average speed of the plane in mph:

\dfrac{525 \,\, \textrm{miles}}{1.75 \,\,\textrm{hours}} = \dfrac{x \,\, \textrm{miles}}{1 \,\,\textrm{hour}}

  • Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that x.

\dfrac{525}{1.75} \,\textrm{miles} = x \,\textrm{miles}

  • Multiply the entire equation by 1 \,\textrm{hour}

\dfrac{525}{1.75} = 300 = x

  • Divide both sides of the equation by 1 \,\textrm{mile} to clear both sides of the mile unit

The average speed of the plane is 300 mph.

David can paint a fence in ten hours. Alex can paint the same fence in eight hours. If
xxTIMURxx [149]

Answer:

40/9

Step-by-step explanation:

Use the work formula, \frac{1}{A} + \frac{1}{B} = \frac{1}{T}, where A is the amount of time it takes one person, B is the amount of time it takes another person, and T is the time it takes for them to work together.

Plug in the times for David and Alex alone:

\frac{1}{10} + \frac{1}{8} = \frac{1}{T}

Find the least common denominator, which is 40.

\frac{4}{40} + \frac{5}{40} = \frac{1}{T}

\frac{9}{40} = \frac{1}{T}

Cross multiply and solve for T:

9T = 40

T = 40/9

So, if they worked together, it would take them 40/9 hours
