Unit Rate of a function
The rate of a function is also known as its slope. According to the question, if an automobile travels 305 miles on 16 2/3 gallons of gasoline, the unit rate is calculated as;
Unit rate = 305/16(2/3)
Convert mixed fraction to improper
Unit rate = 305/(50/3)
Unit rate = 105 * 3/50
Unit rate = 6.3 miles per hour
Hence the miles per gallon does the car get on the trip is 6.3 miles per hour.
To determine how many gallons would be required for the car to travel 549 miles, this is expressed as;
Number of gallons = 549/6.3
Number of gallons = 87.14gallons
Hence the number of gallons required for the car to travel 549 miles is 87.14 gallons
