Question

Emilio can type 60 words in one minute. Mai can type half as many.Together how many words can they type in 3 minutes ?

Answer 1

Answer: 270 words in 3 minutes

Step-by-step explanation:

Emilio: $\frac{60 words}{1minute} *\frac{3}{3} =\frac{180words}{3minutes}$

Mai: $(\frac{1}{2})\frac{60 words}{1minute} *\frac{3}{3} =\frac{90words}{3minutes}$

Emilo + Mai:    $\frac{180+90(words)}{3(minutes)}$

                     = $\frac{270(words)}{3(minutes)}$
