Answer:

134,784 people

Step-by-step explanation:

Hello!

Let's first find the number of people it can carry on 1 trip. We can do this by multiplying the number of people per coach, by the number of coaches.

72 x 12
864

kherson [118]

Answer:

$160\ \text{s}$

Step-by-step explanation:

The inequality that represents the situation is

$500-2.5t$ where $t$ is the time in seconds

$\Rightarrow -2.5t$

$\Rightarrow -2.5t$

$\Rightarrow 2.5t>400$

$\Rightarrow t>\dfrac{400}{2.5}$

$\Rightarrow t>160\ \text{s}$

So, the time after which there will be less than 100 gallons of water is $160\ \text{s}$ .
