A race car can travel 2 laps In 10 minutes How long will it take the race car to complete 100 laps at that rate ?
34kurt

Answer:

500 minutes

Step-by-step explanation:

Ok, so the first thing we want to do is figure out how long it takes to complete one lap.

So if it takes 10 minutes to travel 2 laps lets find out how many minutes for one.

It would be 5 minutes for one lap, if you divide 10 by 2 because of the 2 laps.

Next, you just multiply the 5 minutes by 100 laps:

This gives you 500 minutes.

Hope this helps :)
