Question

2) On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is t= d. How long will it take the airplane to travel 800 miles? Show your work 500

Answer 1

The equation for relation of time with distance travelled is,

`t=(1)/(500)d`

Substitute 800 for d in the equation to determine the time required for travelling 800 miles.

`\begin{gathered} t=(1)/(500)\cdot800 \\ =(8)/(5) \\ =1.6 \end{gathered}`

So airplane take 1.6 hours to travell 800 miles.

Answer: 1.6 hrs
