Question

After 16.5s, a joggers displacement is .200 km. what is the velocity in m/s? what is the velocity in km/hr?

Answer 1

1. 12.1 m/s

2. 43.3 km/hr.

Explanation:

given:

jogger displacement (distance) = 0.200 km

time = 16.5 sec.

find:

1. velocity in m/s

2. velocity in km/hr.

solution:

velocity = distance / time

1. velocity = 0.200 km x 1000 m

16.5 sec 1 km

= 12.1 m/s.

2. velocity = 0.200 km x 3600 sec.

16.5 sec 1 hr.

= 43.3 km/hr.
