Final answer:
The motorcycle can travel 3 km in one second.
Step-by-step explanation:
To find out how much distance the motorcycle can travel in one second, we need to convert the time from minutes to seconds.
There are 60 seconds in a minute, so we can multiply the distance traveled in 5 minutes (3 km) by 60 to find the distance traveled in one minute (180 km).
And then, we can divide the distance traveled in one minute by 60 to find the distance traveled in one second.
Distance traveled in one minute = 3 km × 60 = 180 km
Distance traveled in one second = 180 km ÷ 60 = 3 km.
Therefore, the motorcycle can travel 3 km in one second.
