while Shankar takes path 2.
(1) What do you infer about their speeds?
(11) Who has the greater velocity? Why?​

Answer 1

Answer:

both have equal speed and velocity

Answer 2

Answer:

(1) SHANKAR'S SPEED IS GREATER.

(2) BOTH HAVE EQUAL VELOCITY.

Explanation:

(1) SPEED = DISTANCE/TIME

MANI'S SPEED= 2000m/20 min

MANI'S SPEED= 100m/min

SHANKAR'S SPEED= 3000m/20min

SHANKAR'S SPEED= 150m/min

therefore, shankar has the greater speed

(2) VELOCITY= DISPLACEMENT/TIME

DISPLACEMENT AS WELL AS TIME IS EQUAL FOR BOTH BCOZ THE DISPLACEMENT IS THE SHORTEST DISTANCE BETWEEN THEIR HOME AND MARKET.

SO, BOTH HAVE EQUAL VELOCITY.
