Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).
If you do

, your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
Answer:
57.073 km/h approx.
Step-by-step explanation:
Total distance from Liverpool to Sheffield
= 56 + 61 km
= 117 km
Time from Liverpool to Manchester
=56 km ÷ 70 km/h
=0.8 hours
Time from Manchester to Sheffield
=75 mins
=1.25 hours
Total time = 0.8 h + 1.25 h
= 2.05 hours
Average speed from Liverpool to Sheffield
= 117 ÷ 2.05
= 57.073 km /h

If angle 1 and angle 2 are <u>complementary, </u>then they add up to 90 degrees. We are given that angle 2 equals 52 degrees.
So we subtract and get our answer:
38
That's NOT the final answer.
The next step is:
Angle 1 and angle 3 are vertical angles.
Vertical angles are congruent.
So if angle 1 is 38, then angle 3 is also 38.
Now, supplementary angles add up to 180 degrees.
So that's the answer:
180-38=142
142 is the supplement of angle 3.
Hope it helps! :)

Answer:
0
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
= (-5--5)/ (9--8)
= (-5+5)/(9+8)
= 0/17
=0
The slope it 0
This is a horizontal line because the y value doesn't change. If the y value doesn't change, the slope it zero.
