Question

9. Jill typed 670 words in 15 minutes. If she continues to type at this rate, how many words will

she have typed in 2 hours? (Hint: Convert hours to minutes)

Answer 1

Answer: 5,360

Step-by-step explanation: To find how many in 2 hours, we must convert the hours into mins. So, if:

1 hr = 60 mins

We would do 60 x 2 (since there are 2 hrs) and get 120. So, if Jill can type 670 words in 15 mins, we must do:

120/15

This will give us 8. Now, we multiply to get 670 x 8. That would be 5,360/ Therefore. Jill types 5,360 in 2 hrs, or 120 mins.

Answer 2

Jill will have typed approximately 5,360 words in 2 hours.

Explanation:

To find the number of words Jill will have typed in 2 hours, we need to multiply her typing rate by the number of hours.

First, we need to convert 2 hours to minutes. There are 60 minutes in 1 hour, so 2 hours is equal to 2 * 60 = 120 minutes.

Then, we can multiply Jill's typing rate by the number of minutes to find the total number of words she will have typed. Jill typed 670 words in 15 minutes, so her typing rate is 670 words / 15 minutes = 44.67 words per minute. Multiplying this rate by the number of minutes gives us a total of 44.67 words/minute * 120 minutes = 5,360.4 words. So, Jill will have typed approximately 5,360 words in 2 hours.
