Karen walked three miles in 48 mins. Bob walked one mile further than Karen. If it took Bob 1 hour and 5 min to complete his walk, who walked at a faster rate?

(express as a unit rate please)

Karen

Step-by-step explanation:

Karens speed is 48/3 so 16 minutes per mile. (0.0625miles/min)

Bob walked 4 miles (3+1), which took him 65 minutes (60+5))

This means that his speed is 65/4 so 16 minutes and 15 seconds per mile. about 0.0615miles/min

This means that Karen aren walked at a faster rate.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
