Question

A person starts from a point P and travels along a
path PQRP as shown in the figure. Find the average
speed of the person?​

Answer 1

Answer:

Average speed:- 0.2m/s.

Explanation:

Given:- PQ-4m,. RQ-3m

By Pythagorous,

PR²= PQ²+RQ²

= 4²+3²

= 16+9

PR =√25

PR= 5.

AVERAGE SPEED= TOTAL DISTANCE/ TOTAL TIME.

= (4+3+5)/(20+10+30)

= 12/60

=0.2 m/s.

Answer 2

Answer:

Answer:

Average speed:- 0.2m/s.

Explanation:

Given:- PQ-4m,. RQ-3m

By Pythagorous,

PR²= PQ²+RQ²

= 4²+3²

= 16+9

PR =√25

PR= 5.

AVERAGE SPEED= TOTAL DISTANCE/ TOTAL TIME.

= (4+3+5)/(20+10+30)

= 12/60

=0.2 m/s.
