Answer:

40 miles

Step-by-step explanation:

let distance be d and time be t

Since d varies directly with t, then the equation relating them is

d = kt ← k is the constant of variation

To find k use the condition d = 75 when t = 3

k = [tex]\frac{d}{t}[/tex] = [tex]\frac{75}{3}[/tex] = 25

d = 25t ← equation of variation

when t = 1.6, then

d = 25 × 1.6 = 40 miles
