Answer:
122 km/h
138 km/h
Step-by-step explanation:
distance = speed * time
One bus travels 16 km/h slower than the other
(s * 2) + (s - 16)2 = 520
2s + 2s - 32 = 520
4s = 552
s = 552/4
s = 138 km/h
s - 16 = 122 km/h

Answer:
2x-5
Step-by-step explanation:
f(g(x) means stick g(x) into f(x) in place of x
f(x) = 2x+1
f(g(x) ) = 2(g(x)) +1
and we know that g(x) = x-3
so replace g(x) with x-3
f(g(x) ) = 2(x-3) +1
Distribute
f(g(x)) = 2x-6+1
= 2x-5
