Zach and warren both leave the coffee shop at the same time, but in opposite directions. if warren travels 7 mph faster than zach and after 7 hours they are 161 miles apart, how fast is each traveling?

Speed of Zach = 16 mph

Sspeed of Warren = 16+7=23 mph

Step-by-step explanation:

Let x be the speed of Zach in mph , the speed of Warren will be x+7 mph.

Formula to find distance :-

Then, distance covered by  Zach in 7 hours =

Distance covered by Warren =  

Then, according to the question, we have

Hence, the speed of Zach = 16 mph

The speed of Warren = 16+7=23 mph

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
