Two trains leave a city at the same time. One train goes west at a constant rate of 80 mph. The other goes east at a rate of 60
mph. How long will it take the trains to be 1,050 miles apart?
A. 75 hours
B. 17.5 hours
C. 13 hours
D. 7.5 hours
2 answers:
F(x) = 80x
g(x) = 60x
h(x) = 140x
h(x) = 140(7.5)
so your answer seems to be D
<span>60 + 50 = 110. 550/110= 13 Hours

Answer:
Step-by-step explanation:
Let us say that:
a = black kittens
b = white kittens
We know that:
a = 5 b
a + b = 25
Therefore:
5 b + b = 25
6 b = 25
b = 4.17
But we cannot have a fraction value for the number of
kittens, so round off:
b = 4
So a is:
a = 25 – 4 = 21
