The record for the boston marathon's wheelchair division is 1 hour, 18 minutes, and 27 seconds. the boston marathon is 26.2 miles long. what was the average speed of the record winner of the wheelchair division? round to the nearest hundredth. at this rate, about how long would it take this competitor to complete a 30 mile race?

Given Boston Marathon distance = 26.2 miles = 42164.81 m

And the record time to cover this distance is 1 hour 18 minutes and 27 seconds.

Let us convert that time to seconds = 1*60*60+18*60+27 = 4707 seconds

Average speed =

                          =

Time taken to complete 30 miles(48280.3 meters) at 8.96 m/sec is =

                          = 1 hour 29 minutes 48 seconds

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
