Question

Steve reads 80 pages in 2 hours and 40 minutes. If Cassandra reads twice as fast as Steve, how long will it take her to read a 300 page book? O A 4 hours 40 minutes O B. 5 hours C.5 hours 20 minutes O D. 5 hours 40 minutes

Answer 1

Option B. 5 hours.

Explanation:

Steve reads 80 pages in 2 hours and 40 minutes.

1 hour = 60 minutes

2 hour 40 minutes = (2 × 60) + 40 = 160 minutes

Speed of reading of Steve =
`(80)/(160)`

= 0.5 page per minute

Cassandra reads twice as fast as Steve.

Therefore, speed of reading of Cassandra = 0.5 × 2

= 1 page per minute

Therefore, time to read 300 pages by Cassandra = 300 × 1

= 300 minutes

Now convert minutes to hours

`(300)/(60)`

= 5 hours

Cassandra will take 5 hours to read 300 page book.
