How many calories can burn in 1 hour?

You are doing 1 session of work out.

You jogged 2/3 of the session at 6 miles per hour.

You burn 120 calories per mile you jog.

You walked 1/3 of the session at 3 miles per hour.

You burn 100 calories per mile you walk

• 580

• 500

• 280

• 300

Answer explanation

First, we assume that 1 session is 1 hour.

● Since you jogged ⅔ of the “hour” at 6 miles per hour, that means that you completed 4 miles. ● Multiply 6 miles by ⅓ hour to get 2 miles for every ⅓ hour of jogging

● So ⅔ hour is 4 miles.

● Then you multiply 4 miles by 120 calories per mile to get 480 calories

● Next, we do the same with walking. You walked ⅓ “hour” at 3 miles per hour. That means you completed 1 mile.

● Multiply 3 miles by ⅓ hour to get 1 mile for every ⅓ hour of walking.

● So ⅓ hour is 1 mile.

● Then you multiply 1 mile by 100 calories per mile to get 100 calories.

● Finally, you add up the two numbers.

480 cal + 100 cal= 580 cal

One million students: 2% of them are gifted, 80% of them received their bachelor’s degree and 80% of them receive their masters. What is

• 12800

• 13000

• 16000

• 20000

Answer explanation

● The answer is 12,800 students 0.0128=1.28%<-- if asked for the percent

● If it asks for % it will be 64%

● I don’t recall the question asking for a percentage. The answer I selected was 12,800

Steps:

1. Multiply 1 million x .02 (2% gifted students) = 20,000 gifted students

2. 20,000 gifted students x .8 (80% bachelor’s) = 16,000

3. 16,000 gifted students x .8 (80% masters) = 12,800

What is the size of a $20 bill, & how long would it be in meters if you had $1000 dollars in twenties?

• 7.79

• 7.50

• 7

Answer explanation

First: find how many $20 bills in $1000

20x = 1000

50 $20 bills

Second: Know that a $20 bill is 6.14 inches. Convert to metric system equivalent. Inches are compatible with centimeters. To convert from in. to cm. Multiply by 2.54.

6.14 x 2.54 = 15.59 cm

Third: Multiply by 50 to find the measurement of $1000 in $20 bills like this: $15.59 x 50 = $779.50

Fourth: To convert centimeters to meters, divide by 100 (1 meter = 100 cm). 779.5 ÷ 100 = 7.79 meters
