a leatherback turtle swims at a constant rate of 2.5 kilometers per hour, at its constant rate of speed how long will it take fo

LekaFEV [45]

Hello there!

So, if this turtle is only going 2.5 miles per hour. This would mean that (EACH) hour, this turtle only arrived 2.5 miles. So, we do,

$\boxed{10.0 \left \{ {{2.5+2.5=5.0} \atop {2.5+2.5=5.0}} \right.}$

We would have to count how many ("2.5's" they are above.)

We count only 4.

I would take this turtle 4 miles to swim 10 kilometers.

Simplify quantity 1 over 36 minus 1 over x squared all over 1 over 6 plus 1 over x.

Ne4ueva [31]

[ (1 / 36) - (1 / x²) ] / [ (1 / 6) + (1 / x) ]

[ (x² - 36) / 36x² ] / [ (x + 6) / 6x ]

remember that:
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) ] -------------------- > (x - 6) / 6x

The answer is (x - 6) / 6x
