Question

24. Karl's car uses a gallon of gas every 35 miles, and his gas tank holds 14 gallons when it is full. One day,
Karl started with a full tank of gas, drove 350 miles, bought 8 gallons of gas, and continued driving to
his destination. When he arrived, his gas tank was half full. How many miles did Karl drive that day?
​

Answer 1

Answer:

525 Miles

Step-by-step explanation:

Karl can drive 490m with full(14g) gas tank [ 35*14=490];

Karl drove 350m so he burnt 10g gas [350/35 = 10];

Karl had 4g gas in tank and added 8g more gas so total gas in tank is = 8+4=12g;

Karl left half full (14/2=7)g gas out of 12g gas in tank,

So, Karl used 12-7 = 5g gas to drive anothe 5*35 = 175m.

So Karl drove 350+175 = 525 miles that day.
