Chris and Tracy cross the bridge in 2 minutes. ( The maximum time required by both of them would be 2 minutes)
Then Chris would return with flashlight in 1 minute.
Ashley and Jalen then cross the bridge in 10 minutes.
Now, Tracy will return with flash light in 2 minutes.
Then, Chris and Tracy will cross the bridge in 2 minutes.
<u>Total</u><u> </u><u>time</u><u> </u><u>taken</u><u> </u><u>=</u><u>></u> 2+1+10+2+2 <u>=</u><u>></u> 17 minutes.
