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

Answer:

(a) Sandy has the greatest amount of time.

(b) They read together for $\frac{17}{4}$ hours.

Step-by-step explanation:

Given Bill spent  $\frac{8}{10}$ of an hour reading.

          Carol spent  $\frac{10}{8}$ of an hour reading.

          Sandy spent  $\frac{11}{5}$ of an hour reading.

We know that 1 hour = 60 minutes

So,Time taken by Bill in minutes = $\frac{8}{10}*60$ = 48 minutes.

    Time taken by Carol in minutes = $\frac{10}{8}*60$ = 75 minutes.

    Time taken by Sandy in minutes = $\frac{11}{5}*60$ = 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 $\frac{17}{4}$ hours.
