Question

The aircraft A330 flies at an average speed of 400 miles per hchor. The expression, 400t gives the distance traveled by the aircraft in t hours. Find the distance traveled by the A330 in 6 hours. miles

Answer 1

The expression:

$d(t)=400t$

gives the distance traveled by the aircraft in t hours, so, for t = 6:

$\begin{gathered} t=6 \\ d(6)=400(6) \\ d(6)=\frac{2400mi}{h} \end{gathered}$
