A car with a tank that holds 11.6 gallons of gasoline is using 1.45 gallons per hour. Is the tank more than half full of gasoline after 3.5 hours? Explain your answer.

No, because 11.6/2 is 5.8 so 5.8 is half of the tank. if it uses 1.45 per hour and it's used for 3.5 hours there will only be 5.075

Answer: NO because 5.075g (gasoline available after 3.5 hours) < 5.8g (half full tank)

Step-by-step explanation:

Hi, to solve this problem we have to calculate how many gallons has a half-full tank. If the tank holds 11.6 gallons we have to divide it by 2.

11.6 / 2 = 5.8 gallons (half-full tank)

So, to know if the tank is more than half full of gasoline after 3.5 hours we have to multiply the gallons used in an hour (1.45) by the amount of time (3.5) and compare.

1.45 g/h x 3.5 h = 5.075

In conclusion, after 3.5 hours the the tank is not more than half full of gasoline, because 5.075 < 5.8.
