Answer:
b. 8.7
Step-by-step explanation:
The time he spent running is 13.80 seconds.
<h3>
How much time did he spend running?</h3>
The equation that can be used to represent the time he gets to the tree is:
Time he gets to the tree = (time of each spin x total spins) + time he spent running
21 = (6 x 1.2) + r
21 = 7.20 + r
r = 21 - 7.20
r = 13.80 seconds

the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = - 2 and (a, b) = (2, 6), hence
y - 6 = - 2(x - 2) ← equation in point-slope form
A solution possible for that can be n=25-14,,,therefore n=11....
