### If a one-hour television program has 17.5 minutes of ads, how long is the non-ad content?

• A.

12.5 Minutes

• B.

52.5 Minutes

• C.

82.5 Minutes

• D.

### How long will it take a boy to save \$280 for a video game if he makes \$7 a week delivering papers?

• A.

14 Months

• B.

26 Weeks

• C.

10 Months

• D.

2 Years

C. 10 Months
Explanation
The boy makes \$7 a week delivering papers. To find out how long it will take him to save \$280, we can divide \$280 by \$7. This calculation gives us 40, meaning it will take the boy 40 weeks to save \$280. Since there are 4 weeks in a month, dividing 40 by 4 gives us 10 months. Therefore, it will take the boy 10 months to save \$280 for the video game.

### If your car gets 20 miles per gallon, how many full gallons of gas do you need to drive 273 miles?

• A.

15

• B.

13

• C.

12

• D.

14

D. 14
Explanation
To find the number of gallons of gas needed to drive 273 miles, we divide the total distance by the car's mileage. In this case, the car gets 20 miles per gallon, so we divide 273 by 20. The result is approximately 13.65. Since we can't have a fraction of a gallon, we round up to the nearest whole number, which is 14. Therefore, you would need 14 full gallons of gas to drive 273 miles.

### If seven erasers equal two pencils in length, how many pencils would equal 28 erasers?

• A.

Twelve

• B.

Six

• C.

Eight

• D.

Fourteen

C. Eight
Explanation
If 7 erasers equal 2 pencils in length, then we can find the ratio of erasers to pencils, which is 7:2. To find how many pencils would equal 28 erasers, we can set up a proportion. If 7 erasers is to 2 pencils, then 28 erasers is to x pencils. By cross-multiplying, we find that 7x = 56. Solving for x, we get x = 8. Therefore, 28 erasers would equal 8 pencils.

• A.

Five Hours

Explanation
To find the time it takes to drive a certain distance, we can use the formula: time = distance / speed. In this case, the distance is 420 miles and the speed is 70 miles per hour. Dividing 420 by 70 gives us 6, which means it would take 6 hours to drive 420 miles at a speed of 70 miles per hour. Therefore, the correct answer is Six Hours.
