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

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
