At the beginning of a trip, the tank of Chloe's car was filled with 12 gallons of gas. When she travels constantly on the highway 60 miles per hour, the car consumes 1 gallon of gas per 35 miles. If she traveled 5 hours and 15 minutes on the highway with a constant speed of 60 miles per hour, how many gallons of gas are left in the tank?
Correct answer: A. 3
- A. 3
- B. 4
- C. 5
- D. 6
Explanation
For this to be solved we have to find the gallons of gas used If car travels 60 miles in one hour Car uses 1 gallon for 35 miles let's find the gallons it uses for 60 miles or in an hour 1 /35 x /60 ( cross multiplying) 60 *1 =35*x 12 /7=x Now multiply it with the hours of the journey Time of the journey : 5 hours and 15 minutes 15 minutes in hours :15/60 =¼Gallons used in the journey:5 ¼ * 12 /7 21/4 *12/7 252/28 =9 gallons Now add 9 to the options whichever adds up to 12 is the answer Option A) 3+9=12 Correct Option B) 9+4=13 Option C) 9+5=14 Option D) 6+9=15 None adds upto 12 except A so A is the answer.
