A jet travels 1908 miles against a jetstream in 3 hours and 2178 miles with the jetstream in the same amount of time. What is the rate of the Jet in still air and what is the rate of the Jetstream?

636 miles/hr is the rate of the Jet in still air

726 miles/hr  is the rate of the Jetstream

Explanation:

             Rate or speed = distance / time taken

rate = 1908 miles / 3 hours

       = 636 miles/hr

rate = 2178 miles / 3 hours

       = 726 miles/hr

step-by-step explanation:

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
