Time taken for the boats to meet will be given by:
time=(distance)/(speed)
relative speed=(speed of boat A+speed of boat B)
speed of boat A=2.5 mph
speed of boat B=2(2.5)=5 mph
thus
relative speed=(5+2.5)=7.5 mph
distance=30 miles
thus
time=30/7.5=4 hours
thus the earliest they can meet is 4 hours
The base power is 4 because 6x4 equals 14
Answer:

Step-by-step explanation:
They are alternate interior angles, so they most both equal 80.
9y-1=80
9y=81
y=9
