Answer:
The distance between the two boats after 2.5 hours is 57 m.
Step-by-step explanation:
The distance covered by each boat after 2.5 hours are:
speed = 
distance = speed x time
For boat A, speed = 14 km/h and time = 2.5 hrs.
So that,
distance = 14 x 2.5
= 35 km
For boat B, speed = 18 km/h and time = 2.5 hrs.
So that,
distance = 18 x 2.5
= 45 km
The distance between the two boats after travelling 2.5 hours can be determined by applying the cosine rule. Let the distance be represented by x, so that:
= 
+ 
- 2bc Cos A
= 
+ 
- 2(45 x 35) Cos 
= 2025 + 1225 - 3150 (0)
= 3250
x = 
= 57.0088
x = 57.0 m
The distance between the two boats after 2.5 hours is 57 m.

Answer:
The answer is E.
Step-by-step explanation:
The firm minimizing the cost of production when the input value x is 5 time bigger than y. At the point firm is making maximum profit, then firm need to preserve this ratio. Therefore when the ratio of x/y=5 is the closest ratio that the firm can minimize the cost of the production.
