Answer:
(a) Sandy has the greatest amount of time.
(b) They read together for
hours.
Step-by-step explanation:
Given Bill spent
of an hour reading.
Carol spent
of an hour reading.
Sandy spent
of an hour reading.
We know that 1 hour = 60 minutes
So,Time taken by Bill in minutes =
= 48 minutes.
Time taken by Carol in minutes =
= 75 minutes.
Time taken by Sandy in minutes =
= 132 minutes.
Therefore Sandy takes the greatest amount of time reading.
Now, <em>Time taken by all three when they read together = 48 + 75 +132 </em>
<em> = 255 minutes or </em>
<em> hours.</em>
