Please help question 4

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
