Question

a vehicle moves 45 kilometre in 30 minutes calculate its velocity in metre per second power minus 1 ​

Answer 1

Answer:

45 km= 45000 m

30mins= 1800 sec

Velocity= 45000/1800

25m/s^-1 is the required answer.

Answer 2

Answer:

25 m / sec

Explanation:

Distance = 45 km

Time = 30 minutes = 30 × 60 = 1800 seconds

Velocity is defined as displacement upon time

$v = \frac{displacement}{time}$

$v = \frac{45000}{1800} = 25 \: m \: per \: second$
