Lita typed 2 times as fast as kala. The ratio of the number of words kala typed to the number of words rose typed was 4:1. If rose typed 48 words, how many words did lita type?

Answer 1

For some unit of time:

number of words for kala --- 4x
number of words for rose ---- x
but x = 48, so kala typed 192 words

Since Lita typed twice as fast as kala,
lita typed 384 words
