Answer:
7.3 I think
Step-by-step explanation:
Since Louis jumped 270 times in 6 hours this means that she jumped:

45 times per hour.
Now we need to find how many times she jumped per minute to do this we have to remember that one hour has 60 minutes then we divide the number of jumps per hour by the 60 minutes, that is:

This means that she jumps 0.75 times per minute. Finally to find out how many times she jumped in foour minutes we multiply the 0.75 by 4:

Therefore, Louis jumped 3 times in four minutes.
Answer:
Rate of change = -5.
Step-by-step explanation:
The rate of change is essentially the <u><em>slope</em></u>, m = -5, of the given function,
y = -5x - 5
We know that each number can be divided by two to simplify.
6 / 2 = 3 and 8 / 2 = 4
By dividing, we are getting a simplified version of that fraction.
3 / 4
So Jeremy, in simplified terms, walked 3/4 of the way to school before running 1/4 of the rest of the way.
