Question

A machine can manufacture 50 pens in 12 minutes. How many pens can it manufacture in two hours?

Answer 1

500 pens

Explanation:

A machine can manufacture 50 pens in 12 minutes. How many pens can it manufacture in two hours?

• first of all we convert 2 hours into minutes, 1 hour = 60 minutes, 2 hours = 120 minutes, then we solve with an equation.

50 : 12 = x : 120

x = 50 × 120 : 12

x = 500

-------------------

check

50 : 12 = 500 : 120

25 : 6 = 25 : 6

25/6 = 25/6

the answer is good

Answer 2

500

Explanation:

We know that in one hour, there is 60 minutes. If we need to figure out how many pens are produced in two hours, we can use an equation that looks like this:

60 × 2 (number of hours) = 120 (total minutes)

Now that we know that 120 is the total amount of minutes, we now need to figure out how many pens are produced. If 50 pens are produced every 12 minutes, then we need to figure out how many times 12 goes into 120.

12 × 10 = 120

Now that we know that 12 goes into 120 10 times, we now need to multiply 10 by 50 to get the total amount of pens produced.

10 × 50 = 500

500 pens are produced every two hours,
