1 500/5 = 1000 0.96/0.008 =120s120 is greater than100.

2 0.96/0.008 =120120 * 5 = 600 600 > 500 and run away.

3 500/5 =100100 * 0.008 = 0.8 0.96 is greater than 0.8.

4 0.96/0.008 =120 500/120 = 4. 167 5 is greater than 4.167, run away.

I really can't think of the fifth one. Four data are given in the title, and there are four ways to compare the four data. If we have to say fifth, it should be first, and vice versa. The first one is that the burning time is longer than the time to run to a safe distance, and the fifth one should be that the time to run to a safe zone is shorter than the burning time.

I'll think about it and see if I can add something. ...
