Question

An eastbound car travels a displacement of 80.0 Km in 45 minutes. What is the velocity

of this car in both Km/h and m/s?

Answer 1

Explanation:

d= 80km = 8000m

t = 45 min = 45/60 h

= 0.75 h

V= ?

we know that,

V = d /t

or,V= 80 km / 0.75 h

1. or, V= 106.67 km/hr

or,V= 106.67×1000m / 3600 s

2. or, V= 29.63 m/s
