Answer:
-3/8
Step-by-step explanation:
First rewrite -2 2/3 as an improper fraction: -8/3
Now invert this result: -3/8
This is the reciprocal of -2 2/3.
It will take 8 minutes.
You use a proportion
5/1=2400/x you use 2400 because 2.4km=2400 meters and u need to use the same unit of measurement.
so cross multiplying gives you 5x=2400 which is equal to 480. BUT this is 48 seconds, and it asks you how many minutes, not seconds. So, you divide by 60 because there are 6 seconds in a minute, and you get 8.
The correct answer should be B
That doesn’t give us enough information. there must be something else on your assignment you’re forgetting to give us
Substitute a and c into the formula so you have
2*1/2*9= 9
