Answer: 5.4 hours.
Explanation:
So, this would simply be divison. So, we can take 540 km, and seperate it into 500 km, and 40 km.
That being said, we can divide 500 km by 100, so we can see how many hours it takes for 500 km, which is 5.
Now, we divide 40/100, which gives us 0.4.
Add the two together, and it takes 5.4 hours to reach 540 km at a speed of 100 km/hr
