Kevin walked of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?

Answer: Kevin walked 0.0833 miles per minute

Step-by-step explanation:

Kevin walked a total of miles in 12 minutes. Assuming he walked at a constant speed the entire time, this means that his speed neither increased nor decreased during the time he walked. We want to determine the distance he walked in each minute, this is also seen as his unit rate. It would be determined as follows.

Let the number of miles that Kevin walks in one minute be x

If kevin walked a total of 12 miles in 1 minute, then

Kevin will walk x miles in 1 minute

x = 1/12 = 0.0833 miles per minute
