2.5

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
