Traveling at an average rateaverage rate of between 40 and 50 miles per hour for 4 to 7 hours select the best estimate for the distance traveled. 150miles 315 miles 340miles415miles

Step-by-step explanation:

40 X 4 = 7 X50

160miles = 350miles

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
