Step-by-step explanation:
A plane took 1.5 hours to complete the journey of 915 miles.
Therefore, constant of proportionality will be,
k =
y = 610x
Time in hours (x) Distance in miles (y) Constant
1 y = 610x ⇒ y = 610 miles 610
1.5 915 610
2 y = 2 × 610 = 1220 miles 610
2.5 y = 2.5 × 610 = 1525 miles 610
