Question

Reenu types 540 words during half an hour. How many words would she type in 8 minutes?

(please give the answer with the working)

Answer 1

We will solve this using unitary method.
1/2 an hour = 30 minutes as one hour has 60minutes.
Reenu types in 30 minutes =540 words
So Reenu will type in 1 minute= 540/30= 18 words.
Therefore Reenu will type in 8 minutes= 18*8= 144 words.
Hope this helps.

Time taken = 30 minutes

Letters typed in 8 minutes = ?
