Answer:
b
Step-by-step explanation:
Using the trigonometric identity
• sin²x + cos²x = 1 , hence
cosx = ± 
cosΦ > 0 for 0 < Φ < 
cosΦ =
=
=
=
→ b
8.25 hours is our base number here. 1/3 of it is taken up when he stops at the gas station.
8.25, 4.125 is half of it, 2.75 is our answer for this,
8.25/3 gives you 2.75 due to 2.75 making it 5.5 when doubled and so on
so, the answer is 2 3/4 hours, D
