Two trains travel directly toward each other. One of the trains travels at a rate of 12 km/h while the other travels at a rate o
Schach [20]
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0. 
Now solve the equation: 12t=-20t+72, 
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours. 
Now the equation of the <span>pigeon is like this: x = 48t. 
</span>Then for t = 2.25, we get
 x=2.25\times48=108 km

<span>The Hyde has flown 108 km when the trains meet.</span>

P, Q and R are points in the same
Anna11 [10]

Answer: 119°

Step-by-step explanation:

From the positive y-axis, all angles are measured clockwise

PR = PQ + QR = 5[150°] + 3[60°]

X = 5*sin150 + 3*sin60 = <u>5.1</u>

Y = 5*Cos150 + 3*Cos60 = <u>-2.83</u>

TanA = X/Y

A = -61° = 61° East of South = 119° Clockwise

Therefore, the bearing of R from P is 119°
