Answer:
Slope,
Step-by-step explanation:
It is given that,
A road rises 20 feet for every 100 feet in horizontal distance.
Rise (vertical distance) = 20 feet
Run (horizontal distance) = 100 feet
Slope of the road is given by the ratio of rise to the run. It can be calculated as :
So, the slope is .
200L / 10L
= 20
Since it takes 1 hour to drain 10L, and in order to get 200L you need to drain 10L 20 times, it will take you 20 hours to drain 20L of water
Answer: 20 hours

<em><u>Therefore</u></em><em><u>, </u></em>
Lies between <em><u>4 and 5 (option A)</u></em>
3x+2x=80
5x=80
x=8
