A car travels between two points Pand Q on a straight
road and covers 6km in 5 min. It then turns back
and reaches to a point Rin 4 min covering 4km.
Calculate average speed and average velocity of the car
between
(a) Panda
and
(in Pand R in stunt
Answers
Explanation:
(a) Total distance traveled between P and Q = 6 km
Total displacement between P and Q = 6 km
Then,
Average speed=Total distance/Total Time taken
= 6/(5/60)km/hr
= 72 km/hr
Average velocity=Total displacement/Total Time taken
= 6/(5/60)km/hr
= 72 km/hr
b) Total distance traveled between P to Q to R = 10 km
Total displacement between P to Q to R = 2 km
Then,
Average speed=Total distance/Total Time taken
= 10/(9/60)km/hr
= 60 km/hr
Average velocity=Total displacement/Total Time taken
= 2/(9/60)km/hr
= 40/3 km/hr

do you really want such an easy questions to be asked
now I am sure you are from st. Mary senior secondary school MVP 3
