The question is
How long does it take in minutes to travel 15 kms in a car travelling 90 kms per hour?
I know the answer is 10 minutes, but I'm not sure of the formula.
I tried d=rt or in this case t=d/r but ended up with 0.16666
I know it has something to do with the answer in minutes and the rate in hours.
I need to do these questions in under 1 minute without a calculator for a test.
I just need someone to break it down so I can apply it to any figures.
Thank you.
