The scale on a map is 1: 20 000. (a) Calculate the actual distance between two points which are 2.7 cm apart on the map.
Give your answer in kilometres.

0.54kilometres

Step-by-step explanation:

a)actual distance =2.7*20000

                            =54000cm

                             =0.54kilometres

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
