Please solve question numbe of distance travel chapter

Solution 

Assuming that you are asking the solution for question 17 and 18, we are providing the solution of query 17.
(a) The area under v-t graph gives distance travelled, the distance travelled on both the cases can be calculated as, 
Distance travelled in 0 to 4s = 12×4×2=4 m
Distance travelled in 4 to 6s = 12×2×2=2 m
Therefore, the distance travelled in 0 to 4s is more than the distance travelled in 4 to 6 s.
(b) The slope of v-t graph gives acceleration,
Acceleration in 0 to 4s = 44= 1m/s2
Retardation in 4 to 6s = -42= -2m/s2
For remaining queries, we request you to post them in separate threads to have rapid assistance from our experts.
