Question

The distance a jet aircraft flies has a proportional relationship with its number of hours in flight. The table shows the number of miles flown for a number of hours in flight. Find the constant of proportionality. How long will the jet take to travel 5,880 miles? Passenger Jet Travel Hours 1 2 3 4. Miles 490 980 1,4701,960

Answer 1

Step-by-step explanation:

To find the constant of proportionality we have to divide y by x from the table:

The constant of proportionality is 490. This means that the relation between the hours traveled and the miles is:

`\text{miles}=490*\text{hours}`

If the jet travels 5,880 miles:

`\begin{gathered} 5,880=490*\text{hours} \\ \text{hours=}(5,880)/(490)=12 \end{gathered}`

Answer:

The constant of propotionality is 490

It will take the jet 12 hours to travel 5,880 miles
