If he takes 20 min to reach the field, what is the average velocity of farmer during the walk ?​

Answer 1

Answer:

0.14666

Step-by-step explanation:

Problem Given:

A farmer has to go 500 m due north, 400 m due east and 200 m due south to reach his field.  If he takes 20 min to reach the field, what is the average velocity of farmer during the walk ?​

Solution Of given problem:

Average velocity = Total displacement/Total time taken  

So,

The farmer had a displacement of just 500m and the time taken is 20 minutes ie (60x20=1200).

and if we divide 500/1200 = 0.14666

Answer 2

Answer:

1.5 kmph

Step-by-step explanation:

500m north + 200m south = 300m north and 400m east

so displacement will be √(400^2 +300^2) = 500 m

time = 20 min =1200 s

velocity = 500/1200 = 5/12 * 18/5 kmph = 1.5 kmph
