An Air Force plane left Rome and flew toward Jakarta at an average speed of 255 km/h. A jet left three hours later and flew in the same direction but with an average speed of 408 km/h. How long did the Air Force plane fly before the jet caught up?

if you mean

then it's c. 8, -7/3

but if you mean

then it is

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

the real question is why is this guys last name heavyfoot
