Question

Uma has to put up a fence around her rectangular garden of length 30 M and breadth 20 she takes 10 minutes to complete financing all the sides of a rectangular Garden and comes back to the point where she started from find her average speed and average velocity in metre per second

Answer 1

Answer:

average speed = 60 m / h

average velocity = 0.1666666667 m/s

Explanation:

Perimeter of a rectangular garden

= 2( L + B )

= 2 ( 30 + 20 )

= 2× 50

= 100 m

Uma covers the distance In 10 minutes

So average speed ( per hour)

= (100 /10 )× 6

= 600 /10

= 60 m/hours

and

average velocity = 100 /(10 ×60)

= 100 ÷600

= 0.1666666667 m/s

Answer 2

Answer:

average speed = 60 m/h

average velocity = 0.1666666667 m/s

Explanation:

average speed = 60 m / h

average velocity = 0.1666666667 m/s

Explanation:

Perimeter of a rectangular garden

= 2(L + B )

= 2 ( 30 + 20 )

= 2x 50

= 100 m

Uma covers the distance In 10 minutes

So average speed ( per hour) (100 /10 )× 6

=

= 600 /10

= 60 m/hours

and

average velocity = 100/(10 ×60)

= 100+600

= 0.1666666667 m/s
