This is a uniform distribution. You need to shade the area corresponding to (why) and then say what proportion of the total area it is, either noting that the total area under the line is equal 1 (why?) or using symmetry.

If you need more help, you will need to say exactly where you're still stuck.

Ok thank you, but I am still confused as to which part of the graph that I shade. Could you be more specific as to which part of the graph I am shading, such as the left or right side?

Well, I'd assume that t = 0 corresponds to the class finishing exactly on time. So, with this in mind, go back and think about the values of t I gave in my first reply.
