Please give me answers

Question 1: A car starts from city a and it travels 50 km in a straight line to city B. lmmediately it turns around, and returns to city A. it took 2 hours for this round trip. The average speed or the car for this round trip is :
0 km/h
25km/h
50km/h
100km/h

Question 2: In the total journey the body has travelled up to a distance of
1000m
800m
900m
270m

Question 3: When an object undergoes acceleration
there is always an increase in its velocity
there is always an increase in its speed
a force always acting on it
all of the above.

Question 4: What does the slope of distance - time graph give?
Speed
acceleration
uniform speed
both[a] and [c] depending upon the time of graph

Question 5: An object travels 20m in 5 sec and then another 40m in 5 sec. What is the average speed of the object?
12m/s
6m/s
2m/s
0 m/s

Question 6: The equation v = u + at gives information as
velocity is a function of time .
velocity is a function of position.
positon is a function of time.
positon is function of velocity and time.

Question 7: Distance covered by the body during the interval from 10sec to 20 sec is
200m
360m
270m
400m

Question 8: Acceleration is a vector quantity, which indicates that its value
Can be positive, negative or zero
Is always negative
Is always positive
Is zero

Question 9: A man travels a distance of 20 km from his home to office, and 10 km towards his house back. Then the displacement covered by the man in the whole trip is
30 km
zero km
10 km
50 km

Question 10: SI Unit of measurement of acceleration is
m/s
m/hr
m/s power 2
M

Answer 1

answer1=3 (50km/hr)
answer2=i feel question is incomplete
answer3=all of these
