Mariel can type 150 words in three mins. In how many mina. can she type a manuscript which is composed of 4,050 words

Sagot :

The answer is 81 min. or 1 hour and 21 min.
because 4050 divided by 150 and the answer is 27
and 27 times 3 equals 81
therefore the answer is 81 minutes
  150 : 3 = 4050 : x
x = ( 3 · 4050 ) / 150
   = (3 · 27 )
   = 81
Therefore, Mariel can type 4050 words in 81 minutes or 1h and 21mins.
