Suppose the distance between Istanbul and Lagos is $d$ kilometers and it took the plane $t$ hours to fly from Istanbul to Lagos. Thus \[800 = \frac{d}{t} \mbox{ kilometers per hour.}\] How long does the return trip take? Write an equation, similar to the one above, for the return trip. Solve the two equation. Penny
