The length is 24 and the width is 6.

I did a little guess and check here, as when I algebraically solved it, the answers did not make sense.  However, the length (24) is 4 times the width (6), and 24 times 6 is 144, so it works!

I hope this helps.

A car travels 370 1/2 miles in 6 1/2 hours what is the average speed at which the car is traveling
Alex

Answer:

57 miles per hour

Step-by-step explanation:

Speed is equal to distance over time

I changed the fractions to decimals for ease of math

distance = 370 .5 miles

time = 6.5 hours

Speed = 370.5/6.5 = 57 miles/hour

Extra Points! Solve the equation .
hodyreva [135]

Answer:

  r = -0.1125

Step-by-step explanation:

It works well to subtract 0.5 and convert the percentage to a decimal. You can find the sum by hand or using a calculator.

  r = -0.5 +0.0025 -0.125 +0.51

  r = -0.1125

_____

<em>Comment on the use of a calculator</em>

Many calculators assume that a percentage is to be multiplied by something. If you type this expression into the Google calculator, it will take the % symbol to be an indicator that modulo arithmetic is desired. (It will compute .25 mod -.125 = 0.) So, you need to be aware of how your calculator handles "%". It may be best to do the conversion to decimal before you present the problem to a calculator.
