For this case we have the following inequality:

From here, we define the variable x.
x: number of minutes remaining to finish the race.
From here, we clear the value of x.
We have then:

Therefore, Samuel has less than 22.5 minutes to finish the race in the estimated time.
Answer:
x < 22.5; Sam has fewer than 22.5 minutes left to finish running.

Answer:
A
Step-by-step explanation:
112/0.8 = 140
Use the cosine rule.
c=AB=7
b=AC=8
a=BC=3
a^2=b^2+c^2-2bc(cos(A))
=>
cos(A)=(b^2+c^2-a^2)/(2bc)
=(7^2+8^2-3^2)/(2*7*8)
=13/14
=0.9286
