Karl drove 617.3 miles. for each gallon of gas, the cay can travel 41 miles. select a reasonable estimate of the number of gallons of gas karl used. mark all that apply.
1 1.5
2 1.6
3 15
4 16
5 159

The correct answers are 15 and 16.

Step-by-step explanation:

First we must assume the information.

We know that the total miles traveled is 617.3.

Every 41 miles, Karl spent 1 gallon of gas.

What we need to find out now is to estimate the total number of gallons of gas Karl used.

We will do it with the following equation:

If for 41 miles 1 gallon

For 617.3 miles x Gallon

41. x = 617.3 . 1

And we just have to clear the x:

X = 617.3 / 41

X = 15.05

Because they ask us for an approximate logic result, we can say that the correct options are 15 or 16 gallons of gas.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
