Answer:
4 oil changes
Step-by-step explanation:
Given that:
Distance after first oil change = 5000 miles
Subsequent oil changes = 3300 miles
If distance in miles moved per week = 250 m
Number of weeks per year = 52
Total miles moved per year = (250 * 52) = 13000 miles
Let Number of oil change per year = n
Difference between successive oil change = d = 3300 miles
Using the relation :
Total miles = Ist change + (n - 1)d
13000 = 5000 + (n - 1)3300
13000 = 5000 + 3300n - 3300
13000 = 1700 + 3300n
13000 - 1700 = 3300n
11300 = 3300n
n = 3.424
Hence, number of oil. Changes in first year = 4
I don't know if I am right but I think this is the answer:
If we write beaker with x and content with y
then y=56.8/2=28.4 this is the content of one beaker
so there are two beakers:
2x+28.4=180.4
2x=180.4-28.4
2x=152/2
x=76
