In this problem, we're told that someone covered a total of 21 ,250 feet as a combination of both jogging and walking.
00:17
So 21 ,250 feet is a total distance covered by both jogging and walking in combination.
00:27
We're told that this person walked a total of five minutes walking.
00:44
And 40 minutes of running for a total of 45 minutes of activity, five minutes walking, and we'll say at a rate or a speed of w for walking, and we're told that her jogging rate was twice as fast as her walking rate.
01:20
So we'll say that 40 minutes of running at a jogging rate, that's equal to 2 times w twice as fast as her walking rate or walking speed.
01:34
So a sub an equation to solve for a jogging rate.
01:40
We have 21 ,250 feet covered total.
01:45
That total distance will equal our rate times our times.
01:51
So in terms of the walking portion, if you walk for a total of five minutes, at a rate of w, this is the walking part of of the journey plus another 40 minutes at the jogging rate of 2w, this being the running portion of the journey, or the jogging portion...
