Answer:
S = v1 t1 = 7 t1 traveling downstream
S = v2 t2 = 5 t2 traveling upstream
7 t1 = 5 t2
7 (6 - t2) = 5 t2 since t1 + t2 = 6
42 - 7 t2 = 5 t2
t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs
S = 7 t1 = 7 * 2.5 = 17.5 mi
Also, S = 5 t2 = 5 * 3.5 = 17.5 mi
It’s 9.9 because 3 times 3.3 is 9.9
Answer:
three to five or three over five that one is like division
Step-by-step explanation:
Y=5/4x-4
5/4 is the slope but to pass through the point it needs to cross the y axis at -4
