Answer:
v(b) = 4,5 mil/h speed of the barge in still water
Step-by-step explanation:
d = v*t barge going upstream 12 miles and 4 hours trip
barge returning back 12 miles and 2 hours trip
let call v(b) barge velocity and
v(w) water velocity
d = 12 (Mil) = 4 (h)* [(v(b) - v(w)]
3 = v(b) - v(w) (1)
d = 12 (mil) = 2 (h) * [ (v(b) + v(w)]
6 = v(b) + v(w) (2)
Equations (1) and (2) is a two system equation. Solving
from equation (1) v(w) = v(b) - 3
By subtitution in equation (2)
6 = v(b) + v(b) - 3
9 = 2v(b)
v(b) = 9/2 ⇒ v(b) = 4,5 mil/h
Answer:
125
Step-by-step explanation:
In ΔPTO we are given that
∠PTO = 90° (indicated by the right angle)
and ∠TPO = 35°
And we need to find the exterior angle (∠TOB)
If you didn't know this is the rule about exterior angles
Exterior angles of a triangle are equal to the sum of the opposite interior angles of a triangle
So more specifically for this problem
∠TOB = ∠PTO + ∠TPO
Now that we have created an equation we want to plug in the values that we are given
∠TOB = 90 + 35
90 + 35 = 125
Therefore the answer is 125
