Micah is planning a road trip. He estimates that he will drive a total of of 9 3/4 hours. He wants to stop for gas after 1/3 of the total time has passed. How long will he drive before he stops for gas? Express your answer as a mixed number.

A)13/4 hours
B)9 1/4 hours
C)3 1/4 hours
D)2 1/4 hours

To find how long Micah will drive before he stops for gas, we need to multiply the total time by 1/3: 9 3/4 hours * 1/3 = 39/4 * 1/3 = 39/12 = <<39/12=3 1/4>>3 1/4 hours.

Micah will drive for 3 1/4 hours before he stops for gas. Answer: \boxed{\text{(C)3 1/4 hours}}.
