A car travels 27 miles in 30 minutes. How is the rate in miles/min.
I understand I need to divide 27 by 30 and when I do that I get .90, but then how do I correctly label my answer, .9 miles/min? That doesn't seem like an answer that really makes sense for some reason.
I would label it as this:
velocity= 0.90 miles/minute
it would make more sense to most of us in meters/second, or miles/hour, or feet/second.
velocity(ft/sec)=.9mile/min*1min/60sec*5280ft/mile =79.2 ft/sec
Which brings me to something you need to memorize: 60mph=88ft/sec
velocity(miles/hr)=79.2ft/sec* 60mph/88fps= 54 mph
Thank you. I actually mistyped - the question is what is the rate in miles/min, not how is the rate... but I'll just go with that. I guess it's just not something we see a lot - miles/min.
To determine the rate in miles per minute, you need to divide the distance traveled (27 miles) by the time taken (30 minutes).
When you divide 27 by 30, you get 0.9.
To correctly label your answer, you can say that the rate is 0.9 miles per minute.
It might seem a bit odd because 0.9 miles per minute means that the car is traveling less than a mile in a minute. However, keep in mind that the car's speed can vary, and in this particular case, it is traveling at a rate of 0.9 miles per minute.
