Question

If I had to write 2 pages a day, how long would it take me to write 300 pages?

Answer 1

Time required for writing 2 pages = 1 day

So, time required for writing 1 pages

= 1 day/2

= ½ day

So, time required for writing 300 pages

= ½ day × 300

= (300/2) days

= 150 days

Answer 2

150 days

Explanation:

We can write a ratio to solve

2 pages 300 pages

----------- = ------------

1 day x days

Using cross products

2x = 300

Divide by 2

2x/2 = 300/2

x = 150

150 days
