Question

Problem iD: PRABERUZ On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled 1 in miles, d, to the number of hours flying, t, is t=d. How long will it take the airplane to travel 800 miles? 500 Do not include units (hours) in your answer. copted for free from openupresources.org

Answer 1

We have a relation between the distance traveled in miles (d) and the number of hours flying (t) that is t=(1/500)*d.

Then, when d=800, we have:

$\begin{gathered} t=\frac{1}{500}\cdot d \\ t=\frac{1}{500}\cdot800=\frac{800}{500}=1.6 \end{gathered}$

The time is 1.6 hours.

Answer: 1.6
