We will be using the formulas:
speed=distance/time
time=distance/speed
distance=speed×time
First let's find out Diane's rate of swimming. We can measure this by finding the slope (y/x) of a given coordinate on the graph. One point is (10,15), so you do 15/10=1.5m/s
Now for Rick's rate of swimming, just take a pair of values from the table. 12.5/10=1.25m/s
By the way m/s is metres per second for this
So at a constant speed of 1.5m/s, Diane swam 150m in 150/1.5= 100 seconds, or 1 minute 40 seconds
And at a constant speed of 1.25m/s, Rick swam 150m in 150/1.25= 120 seconds, or 2 minutes.
So the difference between their two times is 20 seconds
Answer:
Your answer is 2.042
Step-by-step explanation:
If you want it simplified you can change it to
2.0/2.04.
The answer to this question is:
9x+8/3x^2
I would pick A because if you look and plug in, you would get all your answers.
A)an=n/(n+1) n= 1,2,3,4,5
a(1) = 1/(1+1) =1/2
a(3) = 3/(3+1) = 3/4
Answer:
-50
Step-by-step explanation:
A negative number is like subtracting money so a withdrawal is an negative number
