Answer:
a)
b) 
Step-by-step explanation:
From the question we are told that:
Distance 
Time of flight 
Flight back 
Generally the equation for Time for flight with jet steam is mathematically given by



Generally the equation for Time for flight against jet steam is mathematically given by



Solving equ 1 and equ 2 simultaneously


Therefore

First, you distribute 0.8 through the parentheses by multiplying 0.8 by s and -12, which gets you to 0.8s-9.6. Now, the equation is changed to 0.3s+0.8s-9.6=33.3. Then, you add like terms (add the two numbers with the s) by doing 0.3s+0.8s which gets you to 1.1s-9.6=33.3, all thats left is adding 9.6 on both sides which gets you to 1.1s=42.9. Now finally, you divide 42.9 by 1.1 and you get 39. The value of s in the equation is 39.
