2.
2.5

Answer 1

Explanation:

A plane took 1.5 hours to complete the journey of 915 miles.

Therefore, constant of proportionality will be,

k =
`(915)/(1.5)=610`

`(y)/(x)=610`

y = 610x

Time in hours (x) Distance in miles (y) Constant
`((y)/(x))`

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
