That's my question

Step 1: State the formula for speed, distance, and time. $v = \frac{d}{t}$ where $v$ is speed, $d$ is distance, and $t$ is time.

Step 2: Rearrange the formula to solve for time ($t$). $t = \frac{d}{v}$

Step 3: Substitute the given values into the formula ($d = 180$ km, $v = 60$ km/h). $t = \frac{180 km}{60 km/h}$

Step 4: Calculate the time. $t = 3 h$

$\boxed{3 h}$
