After completing a speed training, Alyosha translates Russian literature into English at a rate of 10 more than
twice as many words per hour as he was able to translate before the training. If he was previously able to
translate 10 words per minute, how many words can he now translate in an hour?
(A) 30
(B) 70
(C) 610
(D) 1,210
(E) 1,800
Didn't understand this explanation since I adopted this method only:-
Note that you would not want to start by working with the rate per minute. If you did so, you’d get 10 + 2(10) =
30 words/minute, then 30 × 60 = 1,800 words/hr. You would get this inflated number because you added an
additional 10 words per minute instead of per hour. This is another reason to perform your conversions right
away!
