A car is traveling at a rate of 54 kilometers per hour. What is the car's rate in kilometers per minute? How many kilometers will the car travel in 20 minutes?
So first of all, we know that there are 60 seconds in one minute, so lets use that to divide 60 by 54
Alright.. I tried this. 54 km/1 hr x 1 hr/60 min
But after that I was lost.
So when you divide 54/60, you should get 0.9, as 54 is just a tad bit less than 60, so it won't perfectly fit
So what is the 0.9 ?
0.9 is the amount of kilometers driven in 1 minute
We are trying to find 20 minutes, so what is the next thing we do?
Multiply 0.9 by 20 to get 18. (: Thank you for your help!
Your welcome! And if you want further proof, since 20 minutes is 1/3 of an hour, multiply 18 by 3, and you should get 54!
Awesome! Thanks!
