every 20m along a street there are lamppost from beginning to end.

a) the street is 800m long. How many lamppost are there on the street?

b) how many 20m spaces are there along the street?

c) Frankie lives between the lampost 21 and 22. How far from the beginning of the road does his property begin?

a) 800/20 + 1

b) 800/20

c) 20 * 21

a) To find out how many lampposts there are on the street, we need to divide the length of the street by the distance between each lamppost.

The distance between each lamppost is given as 20m.

So, we can calculate the number of lampposts by dividing the length of the street (800m) by the distance between each lamppost (20m):

Number of lampposts = Length of the street / Distance between each lamppost
Number of lampposts = 800m / 20m
Number of lampposts = 40 lampposts

Therefore, there are 40 lampposts on the street.

b) To find out how many 20m spaces there are along the street, we can use the same approach as in part a) since each 20m space corresponds to one lamppost.

Using the length of the street (800m) and the distance between each lamppost (20m):

Number of 20m spaces = Length of the street / Distance between each lamppost
Number of 20m spaces = 800m / 20m
Number of 20m spaces = 40 spaces

Therefore, there are 40 twenty-meter spaces along the street.

c) Frankie lives between the lampposts 21 and 22, which means he lives in the 20m space between those lampposts.

To find out how far Frankie's property begins from the beginning of the road, we need to calculate the distance from the beginning of the road to the beginning of the 20m space he lives in, which is between lampposts 21 and 22.

Since there are 20m spaces between each lamppost, we can simply multiply the number of lampposts before the one Frankie lives between (in this case, 21) by the distance of each space (20m):

Distance from beginning of the road to Frankie's property = Number of lampposts before Frankie * Distance of each space
Distance from beginning of the road to Frankie's property = 21 lampposts * 20m
Distance from beginning of the road to Frankie's property = 420m

Therefore, Frankie's property begins 420m from the beginning of the road.
