Answer:
60 mph
Step-by-step explanation:
Their average speed while driving is ...
speed = distance / time
= (270 mi)/((3 + 1.5) h) = 60 mi/h
The Johnson family averaged 60 mph <em>while driving</em>.
__
Their average speed for the trip is unknown, because we don't know how long the lunch stop was.
Answer:
The angle 
at which the sun is hitting the ground is:
Step-by-step explanation:
You can use right angle trigonometry to solve this, since the man (6 ft tall) and the shadow on the ground (3.5 ft long) form a right angle triangle as shown on the attached image.
The use the tangent function to find the angle that the sun's rays make with the ground:

(2.50$+1.50$)/2=4/2=2$ <span>weighted average
this mean 50 50
750/2=375
</span>375 adult tickets and 375 children's tickets
Answer:
x = 25
Step-by-step explanation:
4x+50 and 150 are vertical angles which means they are equal.
4x+50 =150
Subtract 50 from each side
4x+50-50 = 150-50
4x = 100
Divide each side by 4
4x/4 = 100/4
x = 25
