Answer:
Here we have the case where:
"one chip is eaten in 1/4 mins."
(that means unit rate, the amount of a given variable that we need to do a unit of another variable)
Then the unit rate would be:
4 chips per minute.
Or, in a more mathematical way to write this:
4 chips/min.
Now we could write this in other units, for example.
We know that 1 min = 60s.
Then we have that (1/4) min = 60s/4 = 15s.
Then we have the unit rate:
1 chip every 15 seconds, or:
(1/15) chips/second.
Now, the variable in this case is time, t = time, let's multiply bot our unit rates by the same amount of time, and see if we have the same outcome.
Let's use t = 2 min.
1) (4chips/min)*2min = 8 chips.
2) ((1/15) chips/second)*2min
First, 2 min = 120 seconds.
((1/15) chips/second)*2min = ((1/15) chips/second)*120seconds = 8 chips.
So both unit rates are equivalent.
