Question

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 ?

Answer 1

Karen walked at a faster rate than Bob.

Step-by-step explanation:

To compare who walked at a faster rate, we need to find the speed of Karen and Bob. The speed is calculated by dividing the distance by the time taken. Karen walked 3 miles in 48 minutes, so her speed is 3 miles/48 minutes = 0.0625 miles/minute. Bob walked one mile further than Karen and took 1 hour and 5 minutes, which is 65 minutes. So, his speed is (3+1) miles / 65 minutes = 0.0615 miles/minute. Therefore, Karen walked at a faster rate than Bob.

Answer 2

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
`t=48minutes=(48)/(60)=0.8hour`

Speed is given by
`speed=(distance)/(time)=(3)/(0.8)=3.75miles/hour`

Now Bob walked 1 mile more in 1 hour 5 minute

So distance d = 3+1 = 4

Time
`t=1+(5)/(60)=1.0833hour`

So speed will be
`speed = (4)/(1.0833)=6.692miles/hour`

So Karen walked faster than Bob
