2.765 miles

Step-by-step explanation:

Speed = 6 mph = 6 mile per hour

Time = 27:39, which means 27 minutes and 39 seconds.

So in order to find the distance Parker ran, first we need to convert this time to hours.

There are 60 minutes in 1 hour and 60 seconds in 1 minute. So to convert minutes to hour, we divide the by 60. To convert seconds to hour we divided them by 60 twice, once for converting them to minutes and then to second.

So,

27 minutes and 39 seconds = $\frac{27}{60}+\frac{39}{60 \times 60} = \frac{553}{1200}$ hours

Since, Distance is defined as:

Distance = Speed x Time

The distance hat Parker ran would be:

Distance = $6 \times \frac{533}{1200}=2.765$ miles

This means Parker run for 2.765 miles

Answer from: Quakersoatmeal9

d = 2.76 miles

Step-by-step explanation:

It is given that,

Speed of Parker, v = 6 mph

Time taken, t = 27 minutes 39 seconds = 27.65 minutes = 0.46 hour

Let d is the distance covered by Parker during his motion. We know that the distance covered by an object is equal to the product of speed and time taken. It can be given by :

$d=v\times t$

$d=6\ mph\times 0.46\ h$

d = 2.76 miles

So, the Parker will run 2.76 miles. Hence, this is the required solution.

Answer from: Quest

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
Find the slope of the line parallel to each given line

Find the slope of the line parallel to each given line

Answer from: Quest

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a. $y = 60(1) - 90 \\ y = 60 - 90 \\ y = - 30$ this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b. $y = 60(1) - 150 \\ y = 60 - 150 \\ y = - 90$ this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
