If you can drive 1/6 of the distance every 3/5 of an hour, to find how much of the distance you can drive in 1 hour, you would first figure out what you would have to multiply by 3/5 hr to get 1 hr.
3/5x = 1
x = 1÷3/5 (1 · 5/3)
x = 5/3
Then, you multiply 1/6 by 5/3
1/6 · 5/3 = 5/18
So, in one hour, you can drive 5/18 of the distance
