Answer:
45 km/h
50 km/h
Step-by-step explanation:
Distance traveled in one way = 450 km
Let x = Velocity when he was going to his destination in km/h
He traveled 5 km/h faster when he returned so his velocity was
It took him 1 hour less when he returned so
So, velocity while going to his destination is 45 km/h
While returning his velocity was 45+5 = 50 km/h.
let , $a\ge b$
$\therefore a=G\cdot m$ and $b=G\cdot n$
$a-b=Gm-Gn=G(m-n)$
Now, $\gcd(a-b,b)$ clearly is, $G$
