Question 217129: 1. Fuel consumption, F, varies inversely with speed, S. Therefore, F = K/S.
F is measured in (has the units of ) miles/gallon
S is measured in (has the units of) miles/hr
At 60 miles/hr, fuel consumption is 30 miles/gal
a. What is the value of “k” and what are the units of “k”?
b. What is the fuel consumption at 50 miles/hr?

F+=+K%2FS If F = 30 when S = 60, then:
30+=+K%2F60
K+=+1800
F+=+1800%2FS Substitute S = 50.
F+=+1800%2F50
