We know that
In a period of 4 hours (3 hours of work and 1 hour to refuel)
each street sweepers clean------> 3 miles*3 =9 miles
divide 18 hours by 4
18/4=4.5
4.5 is equal to 4 periods of 4 hours plus 2 hours
Multiply 4 by 9 miles
4*9=36 miles
in the period of 2 hours (<span>in this period there is no refuel)
</span>3*2=6 miles
each street sweepers clean in 18 hours-----> (36+6)-----> 42 miles
two street sweepers clean in 18 hours=2*42------> 84 miles
the answer is
84 miles

The school can buy fifteen notebooks and nineteen tablets. 15X7=105 and 5X19=95. 95+105=200. The first thing you want to do is realize that 5Xanything will give you an answer that has a 0 or a five at the end, so you want to find a product by 7 that ends with a 0 or 5 too.
These types of pieces forces us to think about them, however, it does not matter how it’s the most important, what matters is how it makes you, yourself feel, this kind of abstract art is strictly real and gives us space to think on our own, patterns and unity in work , homogeneity and uniqueness are the most factors that defines the good paint or failure on.
