SOLUTION

At the same time t,

Train 1 would have covered a distance of 80t, since distance = average speed x time.

Train 2 would have covered a distance of 70t.

Now both added should give 210 miles

That is 80t + 70t = 210

150t = 210

t = 210/150

t = 1.4 hours

Determine whether f(x)=5x+1/x and g(x)= x/5x+1 are inverse functions. Explain how you know.
vladimir1956 [14]
A property of inverse functions is that if f(x) = a, g(a) = x

F(x) = (5x+1)/x
G(x) = x/(5x+1)

Plug in x = 3.
F(3) = 16/3
G(16/3) = 16/83. Since it doesn’t equal 3, it’s not an inverse function
