A car travels 172 miles using 7 gallons of gas at this rate how far can the car travel losing 42 gallons of gas

The answer is A. 1,032 miles.
You divide 42 gallons by 7. This is because you know how many miles can be reached per 7 gallons.
41
172
x 6
------
1032

When you divide 42/7 you get 6. You then take 6 and multiply it by 172. 6x2 is 12, you carry the one, 6x7 is 42, plus the 1 that you carried, so you get 43, you carry the 4, 6x1 is 6, and you add the 4 to get 10. This brings your answer to 1, 032.
Isn't 42 gallons six times as much as 7 gallons?
So wouldn't you expect to go six times as far ?
so what is 6(72) miles ?

If a car can travel 172 miles using 7 gallons of gas, then its fuel efficiency is 172/7 = 24.57 miles per gallon.

To find out how far the car can travel using 42 gallons of gas, you can multiply the fuel efficiency by the number of gallons:

distance = fuel efficiency x number of gallons

distance = 24.57 x 42

distance = 1030.94 miles (rounded to two decimal places)

Therefore, the car can travel approximately 1030.94 miles using 42 gallons of gas.
