Question

Bill spent 8/10 of an hour reading carol spent 10/8 are reading sandy spent 1 1/5 hours reading who has the greatest amount of time and how long did they read together

Answer 1

(a) Sandy has the greatest amount of time.

(b) They read together for
`(17)/(4)` hours.

Explanation:

Given Bill spent
`(8)/(10)` of an hour reading.

Carol spent
`(10)/(8)` of an hour reading.

Sandy spent
`(11)/(5)` of an hour reading.

We know that 1 hour = 60 minutes

So,Time taken by Bill in minutes =
`(8)/(10)*60` = 48 minutes.

Time taken by Carol in minutes =
`(10)/(8)*60` = 75 minutes.

Time taken by Sandy in minutes =
`(11)/(5)*60` = 132 minutes.

Therefore Sandy takes the greatest amount of time reading.

Now, Time taken by all three when they read together = 48 + 75 +132

= 255 minutes or
`(17)/(4)` hours.
