Mr. Lyle made a round trip between two cities that were 450 kilometers apart. On the return trip, he increased his average of rate travel by 5 km/h and made the trip in one hour less. Find his rate for each direction.

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.

5/12, or 5: 12
