• A. $12$ min
• B. $13$ min
• C. $14$ min
• D. $15$ min

Answer 1

Answer: (C)

$14$ min

Ramsey : 116 paged book, speed : 1.5 min / page.

Pages read per hour $=\frac{60}{1.5}=40$ pages per hour

Time required to finish book $=\frac{116}{40}=2.9$ hours.

$2.9$ hrs $=2$ hrs $54$ min.

Raymond : 94 paged book, speed : 3 hrs 8 min.

Time required to finish book$=11.38A.M-8.30A.M=3$ hrs $8$ min.

Difference of time in reading the books $=14$ min.
