An airplane flies 2,750 miles in 5 hours. Find the unit rate in miles per second. Round the answer to the nearest hundredth. I appreciate the help very much. I got .132 but I think I'm wrong.
2750 /(5*3600) = .15277
which is .15
there are 3600 = 60 * 60 seconds in an hour
5 * 60 * 60 = 18,000 seconds in 5 hours
2750 / 18,000 = 0.15 miles per second
To find the unit rate in miles per second, we need to determine how many miles the airplane travels in one second.
First, we can calculate the distance the airplane flies per hour by dividing the total distance by the total time: 2,750 miles / 5 hours = 550 miles per hour.
Next, we know there are 60 minutes in an hour and 60 seconds in a minute, so to convert the rate from miles per hour to miles per second, we need to perform two unit conversions.
First, multiply the rate in miles per hour by the conversion factor of 1 hour/60 minutes: 550 miles/hour × 1 hour/60 minutes = 9.17 miles per minute.
Second, multiply the rate in miles per minute by the conversion factor of 1 minute/60 seconds: 9.17 miles/minute × 1 minute/60 seconds = 0.1528 miles per second.
Rounding this answer to the nearest hundredth, we get 0.15 miles per second.
Therefore, the correct unit rate in miles per second is 0.15 (rounded to the nearest hundredth).
I hope this helps! Let me know if you have any more questions.
