Question

During a timed test, Alexander typed 742words in 14minutes. Assuming Alexander works at this rate for the next hour, which of the following best approximates the number of words he would type in that hour?

Answer 1

3,180 words in the hour

Explanation:

First, you have to figure out how many words he types in one minute. Then, have to multiply by the number of minutes. So,

Number of words per minute:

742 = Total number of words in 14 min

14 = time given

742/14 = 53 words per minute

Number of Words in 1 hour:

53 = words per min

60 = number of minutes

53*60 = 3,180

3,180 words in one hour.

Hope my answer helps,

Answer 2

3180 words

Explanation:

We can use a ratio to solve

742 words x words

--------------- = -----------------

14 minutes 60 minutes

Using cross products

742 * 60 = 14x

Divide each side by 14

742*60/14 = x
