+56 As of the first one, you could say that a person drove 130 in 2 hours, therefore if you want to find the speed at which the person drove (mph/miles per hour) you divide both numbers with the number of hours traveled.
calculation:
130/2
2/2
That draws you to the conclusion that the person was driving at a speed of 65mph (miles per hour).
As of the second, you could say that you paid $48 for 4 lbs of flour for example. If you then want to know the price of 1 lbs of flour you would have to divide both numbers by the amount of flour you paid $48 for.
calculation:
48/4
4/4
This tells you that 1 lbs of flour cost $12.
I hope this was helpful, let me know if I misunderstood the question. :)
