Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
Answer:
The distance between the points is 9.219544457292887
Step-by-step explanation:
The distributive property says that a(b+c)= ab+ac
3(2y-7)= 3(2y)+ 3(-7)
Final answer: 6y-21
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
So in this case, the center is (2, -3) and the radius is 4/3.
