Answer:

1.2 hours

Step-by-step explanation:

Recall :

Distance = speed * time

Let the time taken = x

Creating an equation for the question :

Distance of train A + Distance of train B = 192

70 * x + 90 * x = 192

70x + 90x = 192

160x = 192

x = 192 / 160

x = 1.2

It takes 1.2 hours to be 192 miles apart.

Pani-rosa [81]

Answer:

\frac{n}{4}-1

Step-by-step explanation:

If we have a pizza that has n slices and we want to split it between 4 friends, then each friend will get \frac{n}{4} slices.

Now, Harris is one of those friends so he receives  \frac{n}{4}  slices, but he eats one less than he receives. Therefore, we subtract one from this expression to get our final answer of \frac{n}{4}-1.

Hope this helped!

Step-by-step explanation:

Let

The quantity of small tables = x

The quantity of large tables = y

The smaller tables can fit 2 people, the larger tables can seat 4 people.

Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.

Number of people×quantity (small table) + number of people×quantity (large table) = 110

2x + 4y = 110
