Answer:
The Answer is C 252.48 horsepower
Step-by-step explanation:
To the get better understanding of answer above
First we have to understand that it is a rule of thumb that for every 1000 feet the horsepower reduces by 3 percent.
From the question the car horsepower is 300
3 percent of 300 is lost for 1000 feet
x percent of 300 is lost for 5280 feet
3 percent of 300 = (3 ÷ 100) × 300 =0.03
In term of the relationship between loss of horsepower and altitude
0.03 = 1000
x = 5280
cross multiply
= 252.48
