Answer:45 mi/h
Step-by-step explanation:
Recall: Speed = distance / time
Let the time taken for the morning journey be
and the time taken for the afternoon journey be
,and the distance covered be d
that means for the first journey,
30 = 
d = 30 
Also for the afternoon journey,
d = 60 
Equating the two , since the same distance is being covered , we have
30
= 60 
that is
= 
= 2 
Also ,
total distance covered = 30
+ 60 
Average speed = total distance / total time
= 30
+ 60
/
+
Recall that
= 2
, substitute this into the formula for average speed , then we have
Average speed = 30(2
) +60
/ 3
Average speed = 120
/ 3
Therefore :
Average speed = 40 mi/hr
It’s quotient is the answer you get when you decide two numbers. These are both negative integers so you answer will be positive. Basically it is 10/5 which is 2
Answer:
26
Step-by-step explanation:
Substitute the values of r and s into the equation:
10 + r(s - 1 ) =
10 + 4(5 - 1 )

I think it is 1.3 but I’m not sure on it
Answer:
- 70 degrees because all of the angles in a triangle add up to 180 degrees
- 150 degrees because the adjacent angle is 30 degrees
- 110 degrees because the adjacent angle is 70 degrees
- 50 degrees because angle 5 would also have to be 50 in order for all of the angles on that line to be 180 degrees
