I found the answer on the app socratic hope this helps also can u please give me brainliest
First of all, the average speed is the ratio between the distance traveled and the time elapsed. So, the average speed of a car that travelled 720 kilometers in 6 hours is
kilometers per hour.
As for the second exercise, you can simply write this proportion:
Because we expect the distance traveled in 3 hours to be proportional to the distance traveled in 2 hours, if the (average) speed is the same.
Solving for x, we have
<span>[ (1 / 36) - (1 / x²) ] / [ (1 / 6) + (1 / x) ]
[ (x² - 36) / 36x² ] / [ (x + 6) / 6x ]
</span>remember that<span>:
x² - 36 = (x + 6)(x - 6)
so
[ (x+6)(x-6) / 36x² ] / [ (x + 6) / 6x ]
[ (x+6)(x-6) / 36x² ] * [ 6x / (x + 6) ]
6x / 36x² = 1 / 6x
[ (x+6)(x-6) / 6x ] * [ 1 / (x+6) ] -------------------- > </span>(x - 6) / 6x<span>
The answer is </span>(x - 6) / 6x<span>
</span>
Answer:
