<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

John and Elijah are both driving from New York City to Richmond.

John leaves at 7:20 and averages 60 mph (miles per hour) on the way.

Elijah leaves at 7:30 and averages 62 mph on the way.

The situation is modeled by this system, where x is the number of hours after Elijah leaves and y is the distance each will travel.

y = 60x + 10 ...1

y = 62x ...2

The time is taken by Elijah to cross John will be

62x = 60x + 10

2x = 10

x = 5 hours

The distance traveled in 5 hours will be

y = 62 (5)

y = 310 miles

Elijah will pass John after 5 hours, and they each will have traveled 310 miles.

Then the correct option is C.

Find the slope of the line passing through the points (6, -6) and (4, -4)

djyliett [7]

To find the slope (m), use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$ and plug in the two points

(4, -4) = (x₁, y₁)

(6, -6) = (x₂, y₂)

[lines usually go from left to right, so the point furthest to the left is the 1st point]

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-6-(-4)}{6-4}$ [two negative signs cancel each other out and become positive]

$m=\frac{-6+4}{6-4}$

$m=\frac{-2}{2}$

m = -1

Tatiana [17]

The total number of snakes in the zoo is 10.

<h3>How to use ratio to find the number of snake?</h3>

The number of snake can be found using ratio as follows:

The animals in the zoo are lions, tigers and snakes and he has them in the ratio of 5 : 3 : 2. The total animal is 50 animals.

Therefore,

total snakes = 2 / 10 × 50

total snakes = 100 / 10

total snakes = 10

Therefore, the total number of snakes in the zoo is 10.
