Karen walked three miles in 48 minutes bob walked one mile further than karen if it took bob 1 hour and 5 minutes to complete his walk who walked at a faster rate ?

Karen walked faster than Bob

Step-by-step explanation:

We have given that Karen walked 3 miles in 48 minutes

So distance d = 3 mile

Time

Speed is given by

Now Bob walked 1 mile more in 1 hour 5 minute

So distance d = 3+1 = 4

Time

So speed will be

So Karen walked faster than Bob

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
