If working at a constant rate Ahmed takes 1/8 of an hour to complete 6 pages of homework for a statistics company, how long will it take him to do 4 pages of statistics homework?

A. 3 minutes
B. 5 minutes
C. 7.5 minutes
D. 12.5 minutes
E. 15 minutes

Time taken to complete 48 pages is 1 hour.
So, Time taken to complete 4 pages is \(\frac{4}{48}\) hour = \(\frac{1}{12}\) hour

Thus, the time taken is \(\frac{1}{12}\)*60 = 5 minutes...

Hence, the correct answer must be (B) 5 minutes !!

1/8 x 60 = 7.5 minutes
7.5 minutes to read 6 pages

7.5/x = 6/4
7.5(4) = 6x
30 = 6x
x = 5 minutes

Which is answer B

A. 3 minutes
B. 5 minutes
C. 7.5 minutes
D. 12.5 minutes
E. 15 minutes

We are given that Ahmed takes 1/8 of an hour to complete 6 pages of homework. Thus, his rate is 6/(1/8) = 48 pages per hour.

It will take him 4/48 = 1/12 of an hour or (1/12) x 60 = 5 minutes to complete 4 pages of homework.
