Acar travels the speed limit, 65 mph. oceanside is 230 miles away. can it reach oceanside in 4 hours.

3 hours is 195 hours
so 4 hours would be 260
so your answer is 3.6 hours

Same question was posted earlier I repeat my answer here ...

Question (2a):
Given that sum of triangle = 180°
∠1 + ∠2 + ∠3 = 180°
∠3 = 180° - ∠1 - ∠2      (1)

Given that sum of angles on the adjacent line = 180°
∠3 + ∠4 = 180° 
∠4  = 180° - ∠3 (2)

Sub (1) into (2)
 ∠4  = 180° - (180° - ∠1 - ∠2 ) 
∠4  = 180° - 180° + ∠1 +∠2  
∠4  =  ∠1 +∠2  (proven)

Question (2b):
∠4  =  52° + 25° 
∠4  =  77°
