A speed of 45 km/hr is the same as

Correct option is A

Given:

Speed = 45 km/hr

Formula Used:

To convert speed from kilometers per hour (km/hr) to meters per second (m/s):

$$1 \text{km/hr} = \frac{1000}{3600} \text{m/s} = \frac{5}{18} \text{m/s}$$​​

Solution:

1. Given speed = 45 km/hr

2. Convert to m/s:

$$45 \times \frac{5}{18} = \frac{225}{18} = 12.5 \text{m/s}$$​​


Final Answer:
A speed of 45 km/hr is the same as 12.5 m/s .
