write a linear equation to model the situation. you have walked 4 miles on a trail. you continue to walk at a rate of 3 miles per hour for 5 hours.
please tell me how to do this!! thanks!
You have a start point 4 miles from the origin, when this story begins.
You then walk at a rate of speed for a specified time.
There really isn't much equationing (which isn't a word!) to be done here, since you know your speed and time:
Distance from start point =
3 miles per hour for 5 hours
s = 4 + 3 * 5
[<equationing (which isn't a word!)> hehe]
thanks for the help! :)
