The other quantity needed to calculate the average speed is time.
What is average speed?
Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.
Average speed = total distance / total time
For example, if the distance travelled is 100km and the total time is 10 hours, average speed is 10 km/hr (100 / 10).

John walked 9 5/8 miles at an average speed of 1 3/4 MPH. How long did it take John to walk this distance?
Answer:
5 hours and 30 minutes
Step-by-step explanation:
Convert all fractions to decimals for easier division
9 and 5/8 = 9.625
1 and 3/4 = 1.75
Then divide 9.625 by 1.75 to get the hours amount
9.625 / 1.75 = 5.5
0.5 of an hour is 30 minutes, so the final answer is 5 hours and 30 minutes
Answer:
5.5 hours
Step-by-step explanation:
9.625/1.75=5.5hr

Can anyone help me with this
Answer:
(3, -6)
Step-by-step explanation:
Both equations are equal to y, so you can make them equal to each other:
-2x = 5x-21
Get the same terms on the same side by subtracting 5x from both sides"
-7x = -21
Get x alone by dividing both sides by -7:
x = 3
The simplest way to find y is by filling in 3 for x in the first equation:
y = -2(3)
Multiply:
y = -6
Check your answer by filling in 3 for x in the second equation:
y = 5(3) - 21
Multiply:
y = 15 - 21
Subtract:
y = -6
To check both answers together, fill in 3 for x and -6 for y in both equations (although we already checked both answers above):
-6 = -2(3)
-6 = -6
-6 = 5(3) - 21
-6 = 15 - 21
-6 = -6

WILL GIVE BRAINLY PLEASE HELP!!!!!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
Answer:
x ≈ 67.1
Step-by-step explanation:
The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(x°) = 28/72 = 7/18
The angle is found from the cosine using the inverse cosine function:
x° = arccos(7/18)
x° ≈ 67.1°

Answer:
n/4-9 +3
Step-by-step explanation:
to answer this question we have to analyze the information given.
The quotient of a number means the result of the division of 2 numbers.
In this case the numbers are: a number (n) and 4 . n/4
Nine less than that quotient means we have to subtract 9 to the quotient.
n/4-9
Increase by three: we simply have to add 3
n/4-9 +3

Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°

A plant has an initial height of 2 inches and grows at a constant rate of 2 inches each month. A second plant that also grows at a constant rate has an initial height of 1 inch and is 29 inches tall after 1 year. After how many months are the plants the same height?
Answer:
Answer:4.8 monthsStep-by-step explanation:First, let's write down the information that we are given.Plant A: Initial Height: 3 in.Constant Rate of Growth (CRG): 2in/month (2 inches per month)Plant B:Initial Height: 1 in.CRG: 29in/year (29 inches per year)We can see that Plant B grows 29 inches per year, so lets convert Plant B's 'CGR' to months.Plant B - Divide by 12 (12 months in a year)29/12 in/yearNow, Lets put these into equations:Plant A: y = 2x + 3Plant B: y = 29/12 x + 1Now, set these two equations together and solve for x.2x + 3 = 29/12 x + 12 = 5/12 x4.8So, after 4.8 months, the plants will be the same height.
