Zach and Warren both leave the coffee shop at the same time, but in opposite directions. If Warren travels 7 mph faster than Zac
2 answers:
Answer:
The speed of the Zach travelling is 8 miles per hour.
The speed of the Warren travelling is 15 miles per hour.
Step-by-step explanation:
Given : 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.
To find : How fast is each traveling?
Solution :
Let the speed of Zach is x mile per hour.
If Warren travels 7 mph faster than Zach
The speed of the Warren is x+7 miles per hour.
Zach and Warren both leave the coffee shop at the same time, but in opposite directions.
The distance covered is 161 miles in 7 hours.
We know,
Substitute,
The speed of Warren is 8+7=15
The speed of the Zach travelling is 8 miles per hour.
The speed of the Warren travelling is 15 miles per hour.
Answer: 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

So there is a hole or an asymptote at x = 3 and x = -1 and we know, that answer B) is wrong.
2. Asymptotes:
We have only one asymptote at x = -1 (and hole at x = 3), thus the correct answer is A)
We have
