Question

ishwar can read 5 pages in 15 minutes. Anne can read 15 pages in 1 hour. Explain how much longer it would take Anne to read a 300- page book than Ishwar.

Answer 1

Answer: 5 hours

Explanation:

Ishwar's speed per hour:

Number of 15 minute periods in an hour:

= 60 /15

= 4 periods

Ishwar reads at 5 pages in 15 minutes so in an hour Ishwar would read:

= 4 * 5

= 20 pages per hour

Annie = 15 pages in an hour.

Ishwar number of hours to read 300 pages:

= 300 / 20

= 15 hours

Annie number of hours to read 300 pages:

= 300 / 15

= 20 hours

Difference = 20 - 15

= 5 hours
