Question

Sven can type 47 words per minute. How many words would he type in half an hour (30 minutes)?

Answer 1

Ratio problem.

47 / 1 = x / 30

solve for x.

Answer 2

47 words a minute. 47 * 30= ?

Answer 3

You can also use dimensional analysis.

\[30 minutes \times \frac{47 words}{1 minute} = 30(47 words)\]

Answer 4

Notice the "minutes" units cancel when multiplying across, leaving you with words as units.
