# A plane could fly at an average speed of 694 m/s. Calculate how long it would take the plane to fly around the world (which is 4.00 xx 10^7\ "m")?

$\text{16 hours}$

#### Explanation:

Solve it using the formula

$\text{Speed" = "Distance"/"Time}$

$\text{t" = "Distance"/"Speed}$

color(white)("t") = (4.00 × 10^7\ "m")/"694 m/s"

color(white)("t") = 5.76 × 10^4\ "s"

$\textcolor{w h i t e}{\text{t") = 5.76 × 10^4\ cancel"s" × "1 hr"/(3600 cancel"s}}$

color(white)("t") = 16\ "hr"
