Question

Example 3.1: A person walks from point P to
point Q along a straight road in 10 minutes,
then turns back and returns to point R which
is midway between P and Q after further 4
minutes. If PQ is 1 km, find the average speed and velocity in going from p to R​

Answer 1

Answer:

avg. speed between

Explanation:

avg. speed between p,q =10/6 m/s

q,r = 50/24 m/s

1. avg. speed = (10/6 + 50/24 )/2 = 1.87

avg. velocity = 500 m/ 840 s

= 0.595
