A race car can travel 615 miles in 3 hour.A small jet can travel 575 miles in 2.5 hours.write and solve an equation to determine if the car or jet travels at a faster rate
To compare the rates of travel of a race car and a small jet, divide the distance traveled by the time taken for each. The small jet travels at a faster rate than the race car.
Explanation:To determine which travels at a faster rate, we need to compare their rates of travel. The rate of travel is found by dividing the distance traveled by the time taken. Let's denote the rate of the race car as 'r1' and the rate of the small jet as 'r2'.
For the race car, we have r1 = 615 miles / 3 hours = 205 miles per hour.
For the small jet, we have r2 = 575 miles / 2.5 hours = 230 miles per hour.
Comparing the rates, we see that the small jet travels at a faster rate than the race car.

an elevator traveled from the 10th floor to the 2nd floor in 6 seconds. what was the rate of the elevator in floors per second
The elevator travels 4/3 levels per second, or floors per second.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, an elevator traveled from the 10th floor to the 2nd floor in 6 seconds.
Elevator cover total distance = 10 -2 = 8 floors
since it took elevator 6 seconds
thus
elevator travels in 6 seconds = 8 floor
elevator travels in 1 seconds = 8/6 =4/3 floor
Therefore, the rate of the elevator in floors per second is 4/3 floor per seconds

Edwin walks for 2 1/2 hours. He walks 1 2/3 miles in the first hour, 1 3/4 miles in the second hour and 1/4 of the total distance in the last 1/2 hour.What is the total distance Edwin walks?
Answer:
The total distance is 41/9 = 4 5/9 miles
Step-by-step explanation:
Total time is 2 1/2 hours.
First hour, he walks 1 2/3 = 5/3 miles.
Second hour, he walks 1 3/4 = 7/4 miles.
The last half hour he walks 1/4 of total distance. If we call total distance x.
[tex]\frac{5}{3} + \frac{7}{4} +\frac{x}{4} = x[/tex]
Now, we can eliminate the denominator, multiplying by four and by three.
[tex]5*4 + 7*3 + 3*x = 4*3*x\\20 + 21 + 3x = 12 x\\41 +3x = 12x \\41 = 12x - 3x\\41 = 9x\\x = 41/9\\x = 4 \frac{5}{9}[/tex]
Total distance is 4 5/9 miles

converting percent into decimals
Percent means per 100 so 40% 40 per 100, or simply 40/100
When we divide 40 by 100 we get 0.4 which is a decimal number.
to convert from percent to decimal you have to divide by 100, and then remove the % sign.

What is a rectangle?A rectangle is a plane figure that has an equal size of the opposite side. These sides are called the length and the width.
Mathematically;
The area of the rectangle = Length × width
From the parameters given:
Area of a rectangle = 4 1/6 square meters.The width = 1 1/4 metersUsing the formula for the area of a rectangle, we have:
[tex]\mathbf{4 \dfrac{1}{6} m^2 =length \times 1 \dfrac{1}{4} \ m }[/tex]
[tex]\mathbf{ \dfrac{25}{6} m^2 =length \times \dfrac{5}{4} \ m }[/tex]
Multiply both sides by [tex]\mathbf{\dfrac{4}{5}\times \dfrac{1} {m}}[/tex]; we have:
[tex]\mathbf{ \dfrac{25}{6} m^2 \times \mathbf{\dfrac{4}{5}\times \dfrac{1} {m}} =length \times \dfrac{5}{4} \ m \times \mathbf{\dfrac{4}{5}\times \dfrac{1} {m}}}[/tex]
[tex]\mathbf{ length = \dfrac{25}{6} m \times \mathbf{\dfrac{4}{5}} }[/tex]
[tex]\mathbf{ length = \dfrac{5}{3} m \times \mathbf{\dfrac{2}{1}} }[/tex]
[tex]\mathbf{ length = \dfrac{10}{3} m}[/tex]
