Alice cycles to Carla's house at 12 mph and returns by car at 36 mph. If the round trip takes 1 hour, how far away from Carla do

Eduardwww [97]

Answer:

Alice lives <u>9 miles</u> far away from Carla.

Step-by-step explanation:

Given:

Alice cycles to Carla's house at 12 mph and returns by car at 36 mph.

If the round trip takes 1 hour.

Now, to find the distance from Carla to Alice house.

So, let the distance between the houses of Carla and Alice be $x$ .

Now, we solve by using the formula:

Distance/speed = time

Alice cycles to Carla house = $\frac{x}{12}$

And return by car = $\frac{x}{36}$

Time taken for round trip = 1 hour.

Adding both the distance to get the value of x:

$\frac{x}{12}+\frac{x}{36}=1$

$=\frac{3x+x}{36}=1$

$=\frac{4x}{36}=1$

<em>Dividing both sides by 4 we get:</em>

$x=9$

Therefore, Alice lives 9 miles far away from Carla.

I WILL MARKED BRAINLIEST IF YOU COULD ANSWER THIS!

Answer:

s = -2400t + 17400

Step-by-step explanation:

Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.

Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.
