One lap around a track is 1/4 mile. If it takes Mrs. Murphy 1/10 hour to walk 1 lap, what is her walking speed in miles per hour

Stolb23 [73]

Answer:

The speed of Murphy to cover one lap is $\dfrac{1}{40}$ miles per hour .

Step-by-step explanation:

Given as :

The total distance of one lap around track = d = $\dfrac{1}{4}$ miles

The time taken by Murphy to walk one lap = t = $\dfrac{1}{10}$ hours

Let The speed of Murphy = s miles per hour

Now, According to question

Speed = Distance × Time

Or, s = d × t

Or, s = $\dfrac{1}{4}$ miles × $\dfrac{1}{10}$ hours

Or, s = $\dfrac{1\times1}{4\times 10}$ mi/h

Or, s = $\dfrac{1}{40}$ mi/h

So,The speed of Murphy = s = $\dfrac{1}{40}$ miles per hour

Hence, The speed of Murphy to cover one lap is $\dfrac{1}{40}$ miles per hour . Answer

Explanation:

For 2x +4:

group the common factor

2x + 4

and you'll get 2(x + 2)

For 18x + 6:

You'll do the same thing

18x + 6

and you'll get
