a train moves 12 miles in 18 minutes. of the train maintains that speed for 75 minutes, how many miles will it travel.

112.5

Step-by-step explanation:

18 divided by 12 is 1.5

then multiply 1.5 and 75

1.5 x 75 = 112.5

very sorry if this is wrong

18 min=12 miles

1 min=12/18

75 min=12/18×75

if you simplify well you get,

75 min=46 miles

sorry, i can't understand your question. will later if you describe more clearly!

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
