Question

Heather and Mathew take 34 min to walk eastward along a straight road to a store 2 km away. Calculate their velocity.

Answer 1

Answer:

0.98m/s

Explanation:

The average velocity is defined as:

v=\frac{d}{t}v=

t

d

where

d is the displacement

t is the time taken to do the displacement

Here the displacement of Heather and Matt is

d = 2.0 km = 2000 m

While the time interval is

t =34 min \cdot 60 =2040 st=34min⋅60=2040s

So, their average velocity is

v=\frac{2000}{2040}=0.98 m/sv=

2040

2000

=0.98m/s
