Answer:
the x intersept is 3 the y intercept is 4
Step-by-step explanation:
x intersept : 24/8 = 3
y intersept : 24/6 =4
Area=width*height
area=(11.7)*(15.4)
area=180.18cm^2
Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
1 hour = 50 km
3 hours = 50 x 3 = 150 km
Answer: The car would go for 150 km in 3 hours.
