Distance to travel = 20 m.
Let us determine the time, t, that each participant took to complete 20 m.
Barbara:
Average speed = (3 m)/(2 s) = 1.5 m/s
t = 20/1.5 = 13.3 s
Mark:
t = 5 s
Carlos:
y = x + 1
where
y = 20 m
x = time, t
Therefore
t =x = y - 1 = 20 - 1 = 19 s
Summary:
Barbara: 13.3 s
Mark: 5 s
Carlos: 19 s
Answer:
The winner is Mark
Answer:
D. y = 4x − 3
Step-by-step explanation:
Just took the test and got 100%
I think it’s 220m. Since 5 rounds are equal to 1100m then you divide by 5 to see how much he covers in one
Zero
There is no solution for these equations as there is no even one point of intersection between them
Answer:
Step-by-step explanation:
let the number be x
(x+6)/3 =21
x+6=21*3
x+6=63
x=57
