the temperature of a substance increases by 10 degrees celsius in 5 minutes. write this as a unit rate. then convert into degrees fahrenheit per hour.
10/5 = 2
2 degrees celsius in 1 minute
2 degrees celsius = 35.6 degrees Fahrenheit
35.6 * 60 = ____ degrees F /hour
$29/kg is how many cents/g
To write the given information as a unit rate, we need to divide the change in temperature (which is 10 degrees Celsius) by the time taken (which is 5 minutes).
Unit rate = Change in temperature / Time taken
Unit rate = 10 degrees Celsius / 5 minutes
Unit rate = 2 degrees Celsius per minute
To convert this unit rate to degrees Fahrenheit per hour, we need to consider the conversions:
1 degree Celsius = 1.8 degrees Fahrenheit
1 hour = 60 minutes
First, we convert the given unit rate from degrees Celsius to degrees Fahrenheit:
2 degrees Celsius * 1.8 degrees Fahrenheit/degree Celsius = 3.6 degrees Fahrenheit per minute
Next, we convert from minutes to hours:
3.6 degrees Fahrenheit per minute * 60 minutes/hour = 216 degrees Fahrenheit per hour
Therefore, the unit rate, when converted to degrees Fahrenheit per hour, is 216 degrees Fahrenheit per hour.
