Answer: 12:14 pm.
Explanation: 27 minutes after when Sally started, 11:48, is 12:14.
A minute has 60 seconds, therefore we will deal with seconds now
And since we have it that the biker travels 5 feet every 0.5 seconds, lets multiply that by 2 to get the traveled distance per second to make it easier
5*2=10
Finally, multiply 10 feet by 60 seconds(1 minute)
