Answer:
5.83 mins
Step-by-step explanation:
Given;
cleaning of diesel dispensers for 35 min and in that time, cleaning completed is 6 dispensers.
The more the time, the more the number of dispensers cleaned.This is direct proportionality.
Therefore, the time in mins required to clean 1 dispenser
= 35/6
= 5.83 mins
This is same as 5 mins 50 secs.
Answer: 4,840,000 square meters
Each square has an area of (400m)^2 or 160,000 m^2 each square.
There are 390 squares, so:
(30 squares)*(160,000 m^2/square) = 4,800,000 m^2
4,840,000 square meters comes closest
the problem has an infinite number of solutions
Explanation:
3x - 12y = 6
x - 4y = 2
make the coefficient of x same by multiplying the entire following by 3
⇒ ( x - 4y = 2 ) * 3
⇒ 3x - 12y = 6 __ equation 2
3x - 12y = 6 __ equation 1
solving using elimination method:
