The average time the car took to reach each checkpoint are:
<h3>Average time</h3>
Given:
Time interval
1 2 3 4
2.02 3.17 4.12 4.93
2.05 3.07 3.98 4.81
2.15 3.25 4.23 5.01
Hence:
First quarter checkpoint
Average time= (2.02 + 2.05 + 2.15) / 3
Average time=6.22/3
Average time= 2.07s
Second quarter checkpoint
Average time= (3.17 +3.07 + 3.25) / 3
Average time=9.49/3
Average time = 3.16 s
Third quarter check point
Average time= (4.12 + 3.98 + 4.23) / 3
Average time=12.33/3
Average time= 4.11 s
Fourth quarter check point
Average time = (4.93 + 4.81 + 5.01) / 3
Average time=14.75/3
Average time= 4.917 s
Average time=4.92s (Approximately)
Therefore the average time the car took to reach each checkpoint are: 2.07, 3.16, 4.11, 4.92.

2x+3y=6
subtract 2x from both sides.
3y=6-2x
divide by 3 on all sides.
y=2-2/3x
There's an infinite number of equivalent ratios for 27:15, these are the ones that just came to my mind:
27:15 = 54:30 (because 27 * 2 = 54 and 15 * 2 = 30)
27:15 = 9:5 (because 27 / 3 = 9 and 15 / 3 = 5)
27:15 = 135:75 (because 27 * 5 = 135 and 15 * 5 = 75)
130/4000 = 13/400
13/400 = 0.0325
= 3.25%
Soo.. 3.25% of 1500 is your answer
This is how I find percentages..
10% of 1500 = 150
So 5% of 1500 = 75
So 2.5% of 1500 = 37.5
since you are looking for 3.25%, find an answer in between 37.5 and 75, eliminating all answers but C.
The answer is C = 48.7567 grams
20 + 14 + 8 + 28 = 70
70/4(we're dividing by 4 cause the no.of characters is 4)
and = 17.5
