Kevin walked 3/4 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?

We know that Kevin moved at a constant speed, so his movement can be model by:

Where is distance, is speed and is time.

So, we can find the speed first, to then find the expression of the distance at any time:

The ratio of his movement is 1 miles each 16 minutes.

Then, the distance at any minute would be:

This expression model the entire movement of Kevin, because it gives the distance he traveled at any minute.

For example, the first minute, Kevin covered a distance of:

So, we could say that he travels 0.063 miles per minute.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
