*VALUES ON THE DIAGRAM ARE INCORRECT CONSULT ABOVE INFORMATION:
L=2.03  θ = 31.0°

The speed of light in a medium is given by:
$$v_{medium} = \frac{c}{n}$$

Since you have all of this information, you can find the speed. Then, you just need to find the length of the path the light takes in the glass.

$$Time = \frac{distance}{speed}$$


Since you know the width of the block, and can find the angle the light takes through the glass, you can find the path length of the light.

I did that but the website says I got the wrong answer :/

In the block the speed of light becomes c/n.
I think u went wrong when u took the distance light travelled 
distance d travelled would equal t/cos r . r= angle of refraction.t - thickness
