Question

It takes Mike 18 minutes to finish reading 4 pages of a book. If Mike reads each page at the same pace, how long does it take for him to finish reading 30 pages?

Answer 1

THE ANSWER IS AS FOLLOWS

Step-by-step explanation:

LET AMOUNT OF TIME NEEDED BE X

NUMBER OF PAGES - 4       X

AMOUNT OF TIME   - 18      30

CASE OF DIRECT PROPORTION

$\frac{4}{18} =\frac{x}{30}$

=> $\frac{4}{3} = \frac{x}{5}$

=> 20 = 3X

=> X = 20/3 MIN

SO MIKE NEEDS 20/3 MINUTES

Answer 2

Answer:

2 hours 15 minutes

Step-by-step explanation:

Mike can read 4 pages in 18 m

Then, Mike can read 1 page in 18/4 m

Therefore,

Mike can finish 30 pages in 18/4×30 m

so, He can finish 30 pages in 135m

which is 2 h 15 m
