If a marathon runner averages 9.6 mi/h, how long does it take him or her to run a 26.22 mi marathon?
horrorfan [7]

For this case, the first thing you should know is that by definition:

t = \frac{d}{v}

Where,

t: time to travel the distance

d: distance traveled

v: speed

Therefore, substituting values we have:

t = \frac{26.22}{9.6}

t = 2.7h

Answer:

it takes him or her 2.7 hours to run at 26.22 mi marathon

Y=mx+b is the slope intercept form where m is the slope and b is the y-intercept.

We are given that the slope is 7 so:

y=7x+b, using point (3,2) we can solve for b

2=7(3)+b

2=21+b

-19=b so the line is:

y=7x-19
