Question

practice using unit rates in real - world situations.
find the unit rate of miles per gallon for these vehicles
sedan:
minivan:
truck:

vehicle	miles traveled	gasoline used (gal)
minivan	798	42
truck	864	54

Explanation:

Step1: Calculate Sedan's unit rate

Unit rate (miles per gallon) = miles traveled / gasoline used. For Sedan: $630 \div 35 = 18$

Step2: Calculate Minivan's unit rate

For Minivan: $798 \div 42 = 19.0$ (or 19, but 798/42 = 19) Wait, 4219=798, yes. Wait, 798 divided by 42: 4219=798, so 19.
Wait, no, 4219=798? 4220=840, 840-42=798, yes. So 798/42=19.

Step3: Calculate Truck's unit rate

For Truck: $864 \div 54 = 16$ (54*16=864)

Wait, let's recalculate each:

Sedan: 630 miles, 35 gallons. 630/35: divide numerator and denominator by 5: 126/7=18. Correct.

Minivan: 798/42: divide numerator and denominator by 6: 133/7=19. Correct.

Truck: 864/54: divide numerator and denominator by 18: 48/3=16. Correct.

Answer:

Sedan: 18 miles per gallon
Minivan: 19 miles per gallon
Truck: 16 miles per gallon
