Answer:
X>3
Step-by-step explanation:
Answer:
x ≈ 7.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos22° = 
= 
Multiply both sides by 8
8 × cos22° = x, thus
x ≈ 7.4 ( to the nearest tenth )
<span>1st train DATA:
rate = 50 mph ; time = x hrs ; distance = rt = 50x miles
2nd train DATA:
rate = 55 mph ; time = (x-(1/2)) hrs ; distance = rt = 55(x-(1/2)) miles
Equation:
distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)
-5x = -55/2
x = 11/2
x = 5 1/2 hrs (time at which the 2nd train overtakes the 1st train)
