In the time that it takes Car 1 to travel 93 km, Car 2 travels 111 km. If the average speed of Car 2 is 12 km/hour faster than the speed of Car 1, then what is the speed of Car 2? Write and solve a proportion

Answers

Answer:

Car 1=64 km/h

Car 2=74 km/h

Explanation:

The formula for speed is

s=dt

For the first car, we know d

and plugging it into the formula gives us

s1=93t

We know the second car is

12 km/h

faster and the distance is

111 km

, so the formula in terms of the first car's speed would be

s1+12=111

t=s2

Now we can solve for

in the second equation

s1=111t−12

Now we can set the two

equal to each other and solve for

t93t=111t−1293=111−12t=18t=32hours

Now we can plug

into the first car equation to solve for the speed of it

=93 km32h=62 km/h

We know the second car is

12 km/h

faster, so

62 km/h+12 km/h=74 km/h

A gym employee is paid monthly. After working for three months, he had earned $4,500. To determine how much money he will make over a six-month period, he created the table below.

1: If he continues to earn at the same rate, how much will he have earned after working 5 months?
2: After how many months will the gym employee have made $19,500?
3: Write an equation to represent the constant of proportionality.

Answers

Answer: %7,500 , the constant of proportionality would be 1500m (m=one month)

Step-by-step explanation: At this rate, by the time he gets to 6 months he will have made $9,000. Divide this by six to get $1,500 (the unit rate for 1 month). Multiply $1,500 by 5 to get your answer. hope this helps

6. How are slope and rate of change similar ? ( use complete sentence to explain )

Answers

Answer:

Finding Rate of Change. When finding the slope of real-world situations, it is often referred to as rate of change. “Rate of change” means the same as “slope.” If you are asked to find the rate of change, use the slope formula or make a slope triangle.

Step-by-step explanation:

The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . .... if coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.
