A tropical cyclone is approaching a coastal town from $200\text{ km}$ away at a constant speed of $40\text{ km/h}$. How much time do rescue teams have before the cyclone hits the shore?
$4\text{ hours}$
$5\text{ hours}$
$8\text{ hours}$
$10\text{ hours}$
Solution
Using $\text{Time} = \frac{\text{Distance}}{\text{Speed}}$, $\text{Time} = \frac{200}{40} = 5\text{ hours}$.
