Can i have some help plz 56.K.
If you let x be the speed at which Angela ran, you can let x-4 be the speed at which Angela and Kathleen walked. The distance in each direction was 2 miles, and the total time was 45 minutes, which is 3/4 of an hour. Place all of this into a Rate, Time, and distance chart ? (it doesn't have to be a chart but can it be in that form plz...thx )
