Step-by-step explanation:
ty for the points! <3
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
Step-by-step explanation:
You can use PEMDAS to solve this problem from left to right.
First, do 15 ÷ 3 to get 5.
Next, do 2 x 10 to get 20.
Lastly, add 5 and 20 to get 25.
<u>15 ÷ 3</u> + 2 x 10
5 + <u>2 x 10</u>
<u>5 + 20</u>
25
