Yards and meters because they has a good measurement. A mile and kilometer is way to big. A kilometer is 1000 meters and a mile is 5280 feet to be exact.
It would be 9 inches squared, hope this helps!
In this question, it is given that
You start skiing at an elevation 240 ft from the base of the hill and your elevation decreases 8 ft each minute. Your friend starts skiing 320 ft from the base of the hill and her elevation decreases 12 ft per minute.
Let the elevation is represented by h and time by tminutes .
So we have two equations here, which are

And for same elevation, height is same. THat is

THerefore,after 20 minutes, they are at same elevation .
It’s not, and the table would look like this:
Rental time: 1,2,3
Cost $: 37,62,87
895 because 89.5 divided by 0.1 is 895
