Explanation:
I will not complete the answer but I will give you important hints.
Firstly you must consider the distance traveled in the first second. Very simple because any idiot can use s=ut + 0.5at^2
But it is for the next 3 seconds that calculation becomes different. You can use the same formula replacing t=1 with t=3.
SUPER TIP!!
Don't solve the whole equation because to find ratio you just need to divide so you can essentially just cancel all of it off.
