Question

Before Chandra and Bob start reading, Alice says she would like to team read with them. If they divide the book into three sections so that each reads for the same length of time, how many seconds will each have to read?

$6400$

$6600$

$6800$

$7000$

$7200$

Solution:

If all $3$ individuals read the same amount of time, then the number of pages Bob, Chandra, and Alice will read will be in the ratio $4:6:9$ respectively.

This means that they will read $160, 240,$ and $360$ pages respectively. Since they all read for the same amount of time, we can just calculate how long it takes for Bob to read his portion.

Bob will take $45 \cdot 160 = 7200$ seconds to read his portion.

Thus, E is the correct answer.
