Question

a vehicle moves 45 km in 30 minute calculate its velocity in km/h ?

Answer 1

Hi mate !

Distance = 45 km.

Time = 30 mins = 1/2 hrs.

Speed = distance/ time

Speed =

$= > \frac{45}{ \frac{1}{2} } \\ \\ = > 45 \times 2 \\ \\ = > 90 \: km \: h {}^{ - 1}$

Thanks :)

Answer 2

Given - distance or displacement= 45km and time= 30 minute= 1/2 hour we know that velocity =  total distance in given direction or displacement/ total time = 45/1/2 km/hr= 45× 2kn/hr= 90km/hr
