So first find time elapsed
10:40-11:40=1
11:40-12:40=1
12:40-1:10=0.5 or 30 mins
so add
1+1+0.5=2.5, 2 hours 30 mins
3 miles per hour
3 times numberof ohours
3 times 2.5
7.5
answer is 7.5 miles

y=x+3
Answer:
f(x) = 5*cos(5*x) + 2
Step-by-step explanation:
A general cosine function is written as:
f(x) = A*cos(ω*x) + M
where:
A is the amplitude
M is the midline
ω is the angular frequency.
In this case we know that:
The amplitude is 5, then A = 5
The midline is 2, then M = 2
The period is 2*pi/5
The relation between the angular frequency ω and the period T is:
ω = 2*pi/T
Then if the period is T = 2*pi/5, replacing that in the above equation we find that:
ω = 2*pi/T = 2*pi/(2*pi/5) = 5
ω = 5
Then the function is:
f(x) = 5*cos(5*x) + 2
